I'm with the others, 40/20, and that seems consistent with most of the solvers I watch on YouTube too - except for those doing 40+, who need to leave a bit more time for execution.And a quick one for all the experienced mbld folks: is there an ideal breakdown for memo/execution time? Memo is the current bottleneck so I want to work out ideal memo time and work backwards from that. My 7 attempt was just over on time but was doable, if I wanna get crazy and set a goalpost at 10 I should work out how fast the memo needs to be to get there.
To me, MBLD is all about time management. IMHO it's important to develop a good system of blocks, reviews and checkpoints. I do blocks of 4 and aim for 6 minutes per block for initial memo plus one review checking the tracing too. For a 20 cube attempt I therefore have checkpoints for the first 4 blocks at 6, 12, 18 and 24 mins. After that I quickly review those first 16 cubes, for which I budget 5 mins, before doing the last block - so further checkpoints at 29 and 35 mins. That leaves me a 5 minute safety margin, which I do usually eat into. I consider 38 or less quite safe, as I can then afford a steady execution; sometimes I'll run as late as 42 mins in which case I have to rush execution.
