My apologies for causing such a stir, everyone. FWIW, I don't actually think the situation I'm describing should actually happen. It just seems unfair to not get a record for completing the exact same objective faster and in a harder way than normal. Maybe we can have a real discussion when Max or Feliks actually gets a sub 3x3 WR time, one handed, with not a misscramble. Seems unlikely, doesn't it?

At any rate, here are my replies to you all:
If I do 7x7 1 minute but my 6x6 pb is 4 minutes then should the wca count my 6x6 pb as 1 minute too since 7x7 is harder anyway? It’s still basically the same thing and it’s only fair I should get the 6x6 wr too
In 7x7 and 6x6, you solve different puzzles. In 3x3 and OH, you don't.
if I get easy xxcross and LL skip does it also count as FMC WR?
No, because 3x3 and OH are both events where you solve a 3x3 as fast as possible. FMC isn't.
Not really; it doesn't seem there's room for debate. If we allowed this, we'd have to really include all 3x3x3 OH, WF, and BLD results in the regular 3x3x3 results, and that is silly, and requires a lot of overhead. The events are held separately and therefore should be maintained separately. Doing otherwise creates more confusion and more unnecessary work for the WCA.
I agree. It is really silly, and it would create a lot of unnecessary work. But the OH record being faster than the 3x3 record would also be really silly, albeit possible, as Max just showed us!
If this were to happen, it would be enough to say to people who ask, "The fastest ever official solve of a 3x3x3 was actually done as a one-handed solve," or whatever.
There's a decent chance that the people you say this to would say the same thing I did
No. For a time to count in 3x3 you'll have to achieve it by participating in 3x3.
Sure. As the rules currently are. As I said,
should it count?
Everybody gets the same opportunities of 5*(number of rounds) 3x3 solves. Not more.
This does make sense. People who don't do OH are at a disadvantage since they don't get as many solves on to the 3x3 leaderboard. How about if a OH solve only counted on the 3x3 leaderboard for times that beat a 3x3 record, or for someone's personal WCA stats page?
