Speed Stack Timer Version 3 Real

[Andrew Ricci]

You're missing the point.
What he was saying is that you would be unable to fairly compare old results to new results.

For example, if person A from long ago got a time of 5.66 when it was actually 5.664, then changed to 5.660, then person B used the new stackmats and got a time of 5.663, person A would be ranked above person B even though person B was faster.

Don't worry, I do understand the point he's trying to make.

My point is, what other option would there be in order to implement times in the thousandths place? Even if there was a slight inaccuracy with older times, would it really be worth it to use better timers but still scale back to the hundredths due to older results?

Oh, your "I am" comment made it seem like you didn't.

Who says we have to use the better timers?

And its not a "slight" inaccuracy. It's the same inaccuracy that you're trying to fix by using newer timers.

 

[Andrew Ricci]

Who says we have to use the better timers?

No one is. The current timers have proved (from the tests of many people) to be inaccurate, and the new "pro" timers seem to fix these issues. All I'd like to see in future WCA competitions is more accurate results.

You were saying that there would be a problem with the use of the new timers since the old results would not be compatible the new results since they would be rounded differently. The solution to that isn't to alter past results, like you were implying. The solution is to not use the new timers.

 

[Kirjava]

I was gonna join this debate.

Then I realised that WCA won't use the new timers anyway.

Saved me a bunch of time worrying about it.

 

[garcijo]

O think these timers would be very useful in some categories such as Rubik's Magic...

Because it makes a huuuuge difference. The only event in which it would make a moderately sized problem is magic.
Alternatively, the third decimal could be an 'x'.

It does make a difference. The WCA promotes more competitions in more countries with more people and more fun, under fair conditions. This would be an unfair change to regulations because new results are incompatible with old results because of this resolution change (it's resolution, not accuracy or precision, guys.)

Spoiler

Accuracy is how far from the correct value your samples are. Inaccurate would be the timer saying, on average, 1.50 when the actual time average was 1.00.
Precision is the spread of the samples from the mean. Imprecise would be the timer returning a range of 0.50 to 1.50 when the average recorded time is 1.00.
Resolution is the smallest change that can be made to the measurement before a change is made. The new timers have 0.001 second resolution, the "old" ones have 0.01 seconds.

If the thousandth decimal place doens't make a significant difference then why would we consider switching to a new timer?
The only reason that this is an issue right now is that it DOES make a difference.
Take 2x2 finals in Nats 2010 for example.

There's not really a debate as it's well known that the gen2 timers were not very accurate at all. For those who don't know, certain times are not possible/very hard to get on gen2 timers.

As Kir said, the WCA will probably just keep the old ones. Upgrading to new timers costs lots of money for delegates/whoever keeps the timers that are used in competitions.

However, if an upgrade were to happen I think the fairest way to mix the old 0.01 resolution times with new 0.001 resolution times would be to count every 0.01 resolution time as 0.019, for example. Unless someone has some reason involving how the gen2 timer worked internally or whatever that would make this less fair than another method.

Doesn't look anything special more than the 2nd Gen, other than a curved mat. Rounding to the thousandths second? If I ever felt super-spiffy about accuracy, then sure.

Me gusta

translation: me it pleases


Looks slick... hmm... I need a new timer anyway...

 

[cubeflip]

not compatible with displays? what were they thinking?

 

[aronpm]

translation: me it pleases

No, it translates to "I like [it]"

 

[cubeflip]

No, it translates to "I like [it]"

I was doing a direct translation...

EDIT: I meant a literal translation. Me = me, gusta = it pleases.

???

 

[aronpm]

???

Existing displays...

That's not how translation works.

 

[CubeLTD]

Existing displays...

Correct me if I'm wrong, but stack timers connect to displays via the data port?(never went to comp, so I wouldn't know). For V3 it's not "compatible" because it doesn't has a data port( assuming I was correct) But for the pro version I think it should work.

What about in a long term? It makes sense that the WCA would decide to stick with the 2nd Gen. But those timers will be no longer produced in the future.

(it's resolution, not accuracy or precision, guys.)

I encourage people to keep this in mind. Nothing suggests that these new 3rd Gen timers are more accurate.
