[WCA Regulations 2012] Proposed: Alternative formats for 3x3x3 BLD

Do I think an average of 5 should be used for 3BLD? Yes, I do. However, not yet.

:D You're the first person I've seen make this argument other than me. I guess I hadn't thought about how important it would be to have the experience in competition - that makes this argument make even more sense.

I made this argument at least a year ago - that we would eventually get where all the best people are getting almost all solves successful, so there will suddenly be little resistance to going with averages. Back then, no one else seemed to believe me.

I think when we get where the best people have all put the "magical" 10,000 hours into 3x3x3 BLD, they'll practically never miss (maybe I won't have trouble with that average 98/100 by then), and it will just be silly to argue against averages. But I believe that could still be quite a few years from now - 5 to 10 years - far enough away that it's almost impossible to speculate accurately.

I agree with Mike, I would like to see an average for BLD introduced now, but only for statistics, not to determine winners (yet!)

You are missing an important link. If best single counts, everybody will prefer the faster solve against the more safe one... Or at least the fast guys.
They don't care if it is 4/5 or 1/5 if their success solve is fast.

Edit: I mean they will go speed over success rate at all of the 5 solves.

To own or to beat the average WR would be attractive for the fast bld cubers. That would be a very respectable WR to own. I think they would care.
 
I agree with Milan, introducing best of 5 will just make it a further speed contest with more chance to stuff up. It won't improve the accuracy of blindsolvers at all. Skip that stage and go straight to average or don't change it at all.
 
and even if not.. who cares? you will leave the competition knowing that u had the best average and are ranked whatever in the world with it. that's totally fine for me as long as it finds its way into the database. just "losing" the data because of a best of 5 series seems like missing out on something.

Why not change it at all? The people favouring the transition are in the minority - most want to change to best of 5 and leave it like that.
 
Sorry that statement was a bit of a hyperbole. I favour changing either way, but don't really see any reason to favour best of 5 over average of 5.
 
The main issue being raised is how BLD should not be treated like 3x3x3, as the nature of the event is different.

I haven't seen anyone really press that issue to be honest. I haven't thought too much about it, but just off the top of my head, one argument in favour of an average is that, while there is a larger margin for error in bld solving, consistency should still be a goal, even if not as important as raw speed. This is because, without consistency, successes would be few and far between (or at least, not enough for one to be considered a top bld contender). I would be interested to know the history of top bld solvers and their success rates, but probably not worth anyones time to work it out.

This information was just scraped from the WCA result pages. It'd be better to actually query "333bf" events with a "Best of 3" format instead to get a list of successes.

Suggestion:

Possible formats for blindfolded events: Best of 3, Mean of 3
Preferred format for final rounds: Best of 3

Rankings don't change, people can choose to carry on with current DNFy styles, but there is also a mean result recorded. Benefits are that this is backwards compatible. Drawbacks are that it requires people to not consider a number on a list to be vitally important (see 2x2 single debate).

If it's best of 3 and someone gets all three, should they still get a mean in the database (i.e. only round ranking is determined by format)?
If so, what would be done with past rounds with 3 solves? (Fewer solves?)

My wording was bad. I'm saying that rounds of best of 3 should have an average calculated, but that rankings can still be based off of best single. So that nothing we do now changes except that a new score is created. The "winner" of a round as shown on the WCA page is the same. Past competitions with three solves can have an average calculated, but rankings would be unchanged. Competitions with fewer solves would be unaffected.
 
the harder sequence : the best 3 of 5 attempt,then average the 3 attempts < 5 attempt , get rid of the best one and the worst one ,average 3 < mean of 3
at least success/attemp: 3/5 4/5 3/3
the success rate is y : 6*y^5-15*y^4+10*y^3 5*y^4-4*y^5 y^3
if success rate is 90%: 99.14% 91.85% 72.9%
if success rate is 80%: 94.21% 73.73% 51.2%
if success rate is 60%: 68.26% 33.70% 21.6%
if success rate is 40%: 31.74% 8.7% 6.4%
if success rate is 25%: 10.35% 1.5625% 1.5625%
if success rate is 20%: 5.79% 0.67% 0.8%
if success rate is 10%: 0.86% 0.046% 0.1%
 
Seeing the event success rates in Tim's stats post, and in relation to roundy's post above, here are some other BLD stats.

Overall success rate for all competitors that have at least one success: 8390 / 24815 = 0.33810195446303
Competitors without any successes are disregarded on the possibility that they can't actually solve. (the Buck rule)

2011 overall success rate for all competitors that have at least one success: 2873 / 7805 = 0.36809737347854

And looking at top competitors, success rate of all solves from rounds containing solves in the top 100 solves: 133 / 221 = 0.601810

With roundy's numbers above, top competitors would only be getting a third of averages of 5. Overall, only single digit percentages would have successful averages. That would be a pretty ugly change. Any thoughts on my previous suggestion? (Make an average score, but continue to give competition rankings based off of single.)

Thanks to Baiqiang for the stats.
