I did a mbld attempt today, and while it didn't have the best accuracy, the exec/cube and the total time/cube were really awesome for me
52/60 in 58:42
memo was 38:24 which is not terrible but also not decent for me now. I'm usually aiming for 38:00 or less on these 60 cube attempts.
But then exec was 20:18

20.30 exec/cube on a 60 cube attempt wtf
This is by a significant amount, my fastest exec/cube on any attempt where I use my normal amount of reviews. By that I mean, not like how i threw an extra review in for my 52/52 WB or 42/42 NAR, attempts like that.
It's funny, this exec/cube is actually faster than the exec/cube in both my 52/52 WB and 42/42 NAR lol. Those were 20.37 exex/cube and 21.00 exec/cube, respectively.
Also fun things to note about this attempt:
The separate 2pass 12 cube mbld i do at the end of these 60 cube attempts was 12/12 in 9:28! This is my first time ever getting 12/12 with 2pass memo (1 pass for initial tracing and 1 more pass for 1 review)
Also, I made zero memo recall mistakes o_O
4 DNFs were from missing a move, 3 from doing a comm incorrectly, and 1 from tracing wrong.
