Yeah, I just use that to practice finesse.
But when I want to see how fast I currently am, I switch back to standard-zero.
About DAS delay, I never touched the tuning in the options, I instead set the DAS before the game starts (after picking a mode) to 6. I tried setting it to zero but it feels the same? ...or am I not fast enough yet to notice?

I also always use 180 on nullpo, I actually abused it back when my tetris stacking was still really bad, usually doing something like:
But then playing a bit of TF knocked that habit right out of me.

Anyway, sorry for the lack of updates.
I actually had most parts of this "story" already written out, but suddenly, I'm having some radical changes that is totally changing the way I play, and it's making me rethink a lot of the stuff I've already planned out to write.
e.g. (wall-of-text, I tried this around the time Xael recommended high BPM songs)
I tried to memorize a game's bag just to feel how being pro at 40L would be, and to check my current physical limitation (by factoring out the mental limitation part, i.e. thinking). While the idea was ripped off from the thread about becoming
korean sub-25, I usually do this to level up quickly (i.e. back in DDR 3rd mix days, I memorized the first part of Afronova SSR, and my note-reading skill jumped from slow songs like AM-3P and Wonderland, to being able to read any song in that game [I couldn't read fast songs at the time]).
And the feeling was insane. It made me feel that I just had to drop a piece ASAP (or else I would lose precious time). The parts that had very quick drops (e.g. hard-drop x3 quickly, or hold DAS to one side and multiple hard-drops) felt awesome. I started to feel why you would need IRS in such situations (whereas I never even though about needing it myself in the past) rotate-then-drop 3x is sooo much slower than hold rotate, DROPDropdrop.
So I tried doing that in a normal 40L run (drop ASAP, if I can't think about where to place the piece, just put it anywhere good enough, even if I make a hole), and my stacking turned to absolute crap. Especially since I sometimes couldn't even get a decent glance at the previews since I was focusing at the matrix so much (probably due to lack of experience).
I made tons of holes. And I used 118 pieces (instead of my usual 103-105).
And my record jumped to 1:04 from 1:15.
It's insane... I feel like I'm learning bad habits in exchange for speed, I know I should stop but it's just too awesome to play like this.

Gives quite an adrenaline rush. And it exhausts my brain very quickly (I blank out after about 5-6 games, can't even think where to place a piece, it gets quite bad).
