ThisEDIT: Oh I also practised like the first 5 solves with my eyes opened to really see what was going on. I used the old pochmann method, but not BLD. After that I made a very slow memo, wrote it down and looked at the memo when solving for like 5 solves. The I started to do actualy BLD solves by first doing like half of the memo and stop, the other half and scramble + repeat. At like 20 solves done I started to do legit BLDs.
Written memo helps you to focus on just the solving part and you can get much more practice done in a shorter time frame.
I still use this in practicing 4 5 6 BLD.
