Update cumulative cutoff rules #307

Open jfly opened 8 years ago

jfly commented 8 years ago

Under the new regulations, solves after not making the cumulative cutoff should be DNSs: https://github.com/cubing/wca-regulations/pull/353/files. Unfortunately, this is different than the handling of other cutoffs, where the remaining solves are just left blank.

Friendly hint: There is no "cumulative cutoff", but a "cumulative time limit". In particular, such rounds are not "combined", that's why the remaining results are not blanked. Am 16.04.2016 04:32 schrieb "Jeremy Fleischman" notifications@github.com:

Thanks @SAuroux. I keep forgetting that its a combined time limit, not a combined cutoff. Do you happen to know why that is? It seems simpler to me to think of this as a cutoff in a combined round, and then the regulations tweak wouldn't have needed to happen.

Hm, I think I just disagree with you, since for me that is a clear type of time limit. What you call a "regulation tweak" is also just a clarification, nothing has been changed there. :)

Combined rounds need to be basedf on two WCA-official format, usually with "Best of 1" or "Best of 2" being the first format with a result needed to advance to the other format. Such a format could not be fit to any cumulative time limit.

I understand how you think of combined rounds, but AFAIK, the regulations about combined rounds don't say that a combined is comprised of 2 phases, where each phase is a WCA-official format. See 9g, which just says there are two phases.

I'd rather not get hung up on the semantics of what exactly the regulations currently say, though. From a data perspective, I don't like the new regulation clarification, because it won't be possible to tell if someone legitimately DNFed their solves, or just didn't get to do them because of a combined time limit.

If we decided to clarify the regulations as you described them (the first phase of a combined round must be a valid wca format), then I think results team should be keeping track of what format the first phase of the round was. Right now, the database just says "this was a combined round", or "this was not a combined round". Changing that would be a lot of software work, though, and I believe a clean and simple solution would be to leave the leftover solves blank. Then someone looking at results gets a very clear visual indicator from the blank cells that this was a combined round, and they can even guess what the timelimit/cutoff/whatever you want to call it was.
