In the second solve, once you reached
this stage did you notice the lucky block ready to slot into the back-left slot? From here a quick R' U2 R would have done your RH 1x2x2
No, during my solve I did not see that, but now I will look out for similar cases in the future. Normally I solve one block at a time, and I never really thought about doing them simultaneously. Thanks for the tip.
Completed blocks are a gift, so breaking them up is deffo a no no. However, sometimes 'over' analysing for other blocks can hinder the speed too. I've found myself trying to manipulate three completed blocks simultaneously, and all it did was turn it into some kind of FM scenario and slowed me down. Deffo use shortcuts like that, but in moderation. Over optimising requires too much thinking mid-solve. More thought = less speed
