Yah..his speed is amazing. I think it was a store bought cube too! A while ago, I used to do the exPLL on the RyanHeise simulator (in the generator mode), so i first type in all the moves, then after, press Enter. Pressing spacebar will trigger the simulator to do the exact movement that i entered before, only at maximum speed (9 turns per second?). It clocked around 35ish. Of course, in the simulator, if I used an optimal algorithm, it would be even faster...but in real life, it's the fingertricks.
Many years ago, the philosophy was that "The fastest cuber isn't the one with fastest hand, but fastest look-ahead" (loosely quoted from Macky's site). Well now, even though Yu's F2L is around 8 seconds, which nowadays isn't considered super fast, his LL is incredible, probably sub 4 seconds even. And LL is just pure recognition and speedy execution. So now, the one with the fastest hand, even though the look ahead during the F2L isn't great, can easily get 13 seconds (with say, 9-10 seconds F2L). Therefore getting 10-12s isn't that hard. I guess in the past, people haven't got the amazing speed on LL (or at least they thought the 5 seconds LL was the fastest already), so they must relie on the variable speed of the F2L. For me, even if I have a 6 seconds F2L (which I don't get much thesedays because I haven't got the time to practise much), I still choke on LL and end up with 11-12 seconds. It's as if I turn even faster on the F2L than LL o.O (may be because I'm too tired after the F2L

)
So pure turning speed means fast times now? Not just elegant, fluent, non-stop F2L, but rapid LL also? Have speedcubing reached its most no-brainer stage, of just pure speed...? Sigh, I can't keep up lol. On the simulator is so much easier, since I can really go full speed on LL (just typing the algos...not too hard).
anyway...I diverted from the thread topic soo much...sorry. I'm STILL on vacation right now (till August 18th), so i might not be posting much for the time being...
