"WCA shouldn't eat children"
I don't see good disagreement, so it must be a good argument against +2.
Ok sure, but my argument is relevant to the discussion and eating children is not, and there is more to my argument than one irrelevant sentence, and if you go way back in the thread people have actually attempted to counter my argument and failed, so I guess people have seen it as relevant.
I want to clarify this whole situation to make my argument clearer:
A cube is either solved or not solved. There are states that are close to solved, but they are still not solved. The important question is whether these close-to-solved states should be allowed.
So what we have is a situation where someone can only argue about one of two positions: for giving close-to-solved states a +2, or for giving close-to-solved states a DNF.
In forming an argument for one's position, there are two variations on how it can be approached. One can either argue in
favour of their position, or
against the other position.
This leaves us with four ways overall to argue:
1) Argue in favour of giving close-to-solved states a +2
2) Argue against giving close-to-solved states a DNF
3) Argue in favour of giving close-to-solved states a DNF
4) Argue against giving close-to-solved states a +2
In looking at all of these positions, it will become clearer where my own argument sits. So let us look at the arguments presented for each position. Some things to note first though:
- I will try my best to get in all the arguments, but there’s no way I’m going back through this entire thread to find everything.
- I will give one reference for each argument, although many people may have said the same thing.
- Bear in mind that in a lot of cases the argument could be rephrased and put into the other section (i.e. 1 & 2 the same, 3&4 the same), so I just pick one or the other with whatever I think sounds better.
- I have not looked at any posts since keyan bumped the thread three weeks ago, as I can’t recall anything new being added.
- There may be a bias towards my own position, although I have tried to keep things neutral as much as possible.
- This is a bit of a mess, and I have decided I can’t be bothered to organise everything in some way, so I have mainly left things in chronological order (this may also help to not bias things).
1) Argue in favour of giving close-to-solved states a +2
blade740:
- +2 is enough to penalise sloppy cubers; it is a harsh enough penalty
Radu:
- It gives a safety barrier for the limitations of our timing procedure, whereby a cube is dropped and turns by itself
Kian:
- +2 is severe enough to be useful but not so severe as to be ridiculous and capricious
Zane Carney:
- Anyone who can get a puzzle one move from solved has clearly demonstrated they know how to solve it. A small error shouldn't prevent someone from getting that recognised
Michael Gottlieb:
- Starting and stopping the timer is not part of solving the cube, therefore a protective buffer is necessary for unlucky situations
BlueDevil:
- +2 is already more time than it would take to make the final move, so it’s enough of a penalty
Stefan:
- It is the status quo
2) Argue against giving close-to-solved states a DNF
Sebastien Auroux:
- The community is not ready for this change
MadsMohr:
- Judge rulings could be harder to make with more on the line
blade740:
- This would hurt inexperienced cubers but won't help anyone
- It could potentially invalidate hundreds of results
Radu:
- It will be a disadvantage for the good cubers who might miss an average and not get in to the next round, just because of a rush or unluckiness
emolover:
- Many people would DNF way too often
Michael Gottlieb:
- Having no leniency is frustrating, and would end up making it easier to mess up
- If you get an early DNF it’s just luck whether you will get an average or not
- There is an intuitive fairness aspect: if you get a misalignment that isn't your fault, and are given a +2, that's acceptable, but a DNF would make competitors feel like it’s way more unfair and frustrating
Stefan:
- It would make tough decisions on the 45° cut-off much tougher, with more on the line, and competitors may not find decisions as reasonable with the harsher penalty
fatboyxpc:
- Knowing that there is a threat of a DNF will affect the meta of competitors, causing them to take more care at the end of their solves, resulting in slower times (this is particularly significant with regards to single WRs)
Florian:
- Competitions should be about fun, and giving competitors a DNF for a simple mistake, potentially taking them out of future rounds, would take that fun away
3) Argue in favour of giving close-to-solved states a DNF
Olivér Perge:
- Dropping the cube as opposed to placing it down does not save much time (refer
Lars Vandenbergh’s video)
- A safety net of 45° is enough
- It would solve the problem of having the same penalty for magic and 7x7x7
MadsMohr:
- This gives our sport a more mature and professional/serious image.
Olivér Perge:
- It removes the problem with slice turns counting as two moves, even if executed as one
- The actual solve process and required final position are the same, so nothing about what the competitor should be doing is changing
- There is more consistency with errors within the same solve. If an error of one move is made earlier in the solve (e.g. wrong AUF before executing PLL) it is punished equally to a one move error made at the end of the solve. Put another way: there is no fundamental distinction between any given move during a solve, but two moves could be treated differently
- Finishing the puzzle properly is the part of the whole solve
Olivér Perge:
- Getting more than one solve with a misaligned slice in an average is not that common, therefore DNF is not too harsh a penalty
- People would get used to finishing their solves properly quickly enough
Clement Gallet:
- Brings about consistency between events, as there is no alternative for a misaligned slice on clock
- Removes weird cases, such as on Square-1, where (0,-1)/(1,1) is counted as solved with penalty, when it looks like a DNF
Dan Cohen:
- Even though it may be frustrating, having no leniency already works on clock, and therefore it would work on other puzzles too
liljthedude:
- A puzzle is either solved or not solved; there is no grey area, so there shouldn’t be grey are in how we judge it
keyan:
- Fairness in “luck” (or “bad luck”): If a cube drops onto the table and turns by itself, this is treated less harshly than a cube that drops onto the table and pops
- Fairness between “chance”: If during a BLD solve one move is done incorrectly, by chance it ends up with one layer misaligned, but one move done incorrectly and any other point in the solve could leave it off by three pieces. In this case, chance is determining how much “luck” or “bad luck” that we allow
Gilles Roux:
- Luck has nothing to do with it; cubers can perform optimally hundreds of move sequences, so it is not a lot to expect that they perform their last move correctly
keyan:
- This brings about simplicity, by only having two classifications: solved and not solved
reThinking the Cube:
- A DNF is an appropriate ruling for a puzzle that has not been finished; pseudo-times should not be given for pseudo-solves
Lastly for this section, in response to the meta-argument,
this post and the following discussion are of interest. What people make of it is up to them.
4) Argue against giving close-to-solved states a +2
Olivér Perge:
- It creates the issue of trying to explain to non-cubers and the media why a cube with a misaligned slice is valid
MadsMohr:
- If you can't complete the task more than three times out of five then you don't deserve a result
Olivér Perge:
- Getting a +2 is largely a result of rushing at the end of a solve and is a bad habit which is not hard to change
Olivér Perge:
- Unfairness, in that the same penalty of +2 is given, for example, for touching the puzzle before starting the timer, which is much harsher
Dene:
- It is the competitors fault if there is a misaligned slice, therefore they should be prepared for the consequences of it occurring
Zane Carney:
- The +2 rule could be used deliberately to one’s advantage (although this would most likely only apply to feet or BLD)
keyan:
- The only reason people want to keep the +2 rule is because they are scared
Dene and
Dene
- The WCA should not have to account for the risks that competitors take, nor their laziness. Starting and stopping the timer correctly is part of the procedure and everyone has that knowledge before going into a solve, therefore the decision to drop the cube rather than place it down, is a conscious risk taken by the competitor. Also, leaving a cube in a state that is around about 45° is the risk competitors take by not ensuring that the finish each turn properly, therefore the delegates ruling on difficult cases should be final
END OF ARGUMENTS
So what can we make of all of this giant mess? Well, there are a lot of arguments for each position, although the most have been given in favour of the DNF rule, so hopefully that will satisfy Sebastien. But which stance has the strongest arguments? I guess that is up to the WRC. I would give my own analysis but I'm pooped. This post took me all day to make (on and off) and I just can't be bothered. I'll wait for feedback and respond to that >.<
