I did some analysis of my TGM 1 PB video and wanted to share some of my findings here. This was the first time I've really gone this in depth with it and I found it really eye opening. I encourage you to do the same. Basically, I tracked through my video noting section times, line clears, and level stops (VLC frame advance helped me not lose my sanity with this) and I compiled all this data into a spreadsheet. Here's a screen shot of the data: I truncated the times to tenths of a second as I figured that was good enough. I defined the level stop start as when the first piece on level x99 locked down, so if the first piece at level x99 cleared a line, the level stop was 0 seconds. Looking at this you can probably notice a number of things, but let me point some things out. I clear way more singles in the second half (20g) than I do in the first half (pre-20g) - almost 4 times as many I clear way more tetrises in the first half than I do the second half - over 5 times as many Level stops weren't a big factor in this game Since the line clear animation takes 41 frames (at 60 frames/second, that's about 0.68 seconds), clearing 4 singles takes 164 frames (about 2.73 seconds) - 123 more frames (2.05 seconds) than clearing 1 tetris. This time adds up: by my calculations if I had cleared 14 tetrises and 1 triple instead of the 59 singles (all other things being the same), I would have shaved about 30 seconds off my time. Since I found the Avoid the Single thread, I've been consciously trying to reduce the number of singles I clear when I play. I think this has paid off in the first half of the game, but clearly I need to stack better in 20g. Even though level stops weren't a big factor in this game, I know that they sometimes are for me. Maybe I got lucky on this game. Maybe I'm getting better about level stops. I really need to analyze more games to get a better idea about this. I think one of the best things about this exercise is that it can challenge the assumptions you have about your play. Going into this, I kind of expected to find that my 20g was better than my pre-20g play, but now I see that I have a lot more "free" time in 20g than I realized. I also expected to have had a lot more time spent at level stops. I know this analysis has its limitations - it doesn't take into account placement decisions, finesse, hesitation (e.g. not charging DAS during ARE or changing your mind on a placement), etc. The analysis takes some time, but I think it's worth it. It looks like I'll be spending more time practicing with the 20g code. If you're wanting to improve your times, post your own analysis of your game(s) or point out things you notice from other people.
