DNS for pre-signing: No competitor should have the natural instinct to sign for future solves. We just want to warn competitors who have been doing that because they tried it once and no Delegate has stopped them.
So, no one should get a DNS unless they're trying to do the wrong thing. We're giving ample warning, and Delegates should be able to handle honest accidents.
3BLD is not affected directly by this since it's not an event under 9b2), so it will only affect Rubik's Cube: With Feet, Rubik's Cube: Fewest Moves, 6x6x6 Cube, and 7x7x7 Cube.
But "forcing the hand" for all Best of 3-attempts to be Mean of 3's makes the potential addition of 3BLD to this category (as an option to organizers) very improbable in the near future.
The WCA/Board can decide on any changes they want. If the community is interested in mean of BLD competitions without forbidding best of 3 competitions (which is unfortunately very inconsistent), we can create a new Regulation to handle this case.
No. If you read 9b3, you'll see that Mean of 2 is not an official round format. It's also much simpler if only one kind of mean is ranked per event (else you'd have to compare means of 2 with means of 3, or have two mean rankings).
I'm not totally sure about this, and have me wondering for the whole year of 2013, is solving on a mat a must for feet solving?
I'm usually faster on a hard surface than on the mat (since I don't have one to practice on at home), however since I translate the regs last layer, I thought I read something about solving on the mat is a must somewhere, but then I can't recall the part that made me think so nor can I find it.
One thing I would like to see is the statement that .5 rounds up for times over 10 minutes. Some places teach round even, which could cause irregularities. It is given in the example, but not clearly stated.
