On what grounds can/should delegates discard/filter scrambles then? Should F2L-skip be discarded? What about xxx(or xx or x)-cross skip be discarded? What about 1-2 moves away from any of the before mentioned cases?
Also it is good to remember that 2x2 single WR is done with a 4 move scramble. That wasn't discarded either and all the records made with that scramble still stand official...
So to answer your question: Yes I really think records from such scramble would(or at least should) be allowed to stand because all results from a 4-move 2x2 scramble are already official and that's also ridiculous.
At present there are no grounds, because basically it's easier to cross our fingers and hope it doesn't happen than to actually make a decision about it.
I realise 2x2 single is retarded. I have argued on many occasions to remove the acknowledgement of 2x2 single WR (and 2x2 in general). Anyway, a 4 move scramble on a 2x2 isn't that unlikely (think: we have on average about 10 competitions around the world in a week. Let's guess on average 2 rounds of 2x2 per comp, with 2 groups in first round. So 3 lots of scrambles, with 7 scrambles per sheet, so 21 per comp, 210 per weekend, more than 10000 per year). On the other hand, a T-perm on a 3x3 has a one in 43 quintillion chance of showing up.
Interestingly, I know Tyson Mao isn't a fan of 3x3 single. Personally I still think the record has some worth, as long as we don't let it get to a point where it is something retarded like a T-perm.
Bear something in mind: we delegates don't work in total isolation. We regularly communicate via a google group, which also includes the regulations committee and the Board. If something like a crazy easy scramble showed up, we could just send everyone an e-mail and figure out what to do in real time (this is something that already happens with unusual situations that show up in comps).
Another thing to bear in mind: The regulations aren't like The Bible, written by the guided hand of the Holy God.
We, as a
community, work together to create the regulations. We can make them as we please, and change them at a whim. So ask yourself: if some retarded scramble showed up in some random competition somewhere and people were getting sub1 solves on 3x3, do you think we should just accept it and leave it like that forever, or do you think we would agree as a community that it's an anomaly that should be fixed so it doesn't ruin everything? I mean, we could always set those records aside (rather than DNFing them) and have a separate category (kind of like wind assisted sprints).
