XaeL: I'll try this. But I instinctively try and hold pieces. Does not holding really make one go faster? Also what's a PB? I've tried using the Tetris only method and I fail miserably at this.
PB means Personal Best. Maybe you focus not much enough on the next piece(s). One reason may be that you use hold too much. Disable the hold key and see how you perform. I sprint without hold. I play the Quadruple style (leaving one column on the wall empty for I pieces) but I also do a lot of skimming. My stack is lower towards the empty column (looks a bit like a funnel, 1 wide with some rows of 2 wide or 3 wide on top) so I can skim most pieces.
Another reason for not focusing (fast) enough on the next piece is that you are distracted by 3+ previews. In NullpoMino you can limit the number of previews to 1 or 2 by using ruleditor.bat (open Standard???.rul, enter 1 or 2 under # of piece preview, save). Don't look actively at the next piece queue. Look at the ghost piece instead (or a little above) and perceive the next pieces in your peripheral vision. Also make sure that the next piece queue is displayed on the side and big (general options -> next display type).
For training purposes you can also try to make the current piece disappear (current piece over the top, ghost piece deactivated). You do so again by editing a rule (or creating a new rule) in the ruleeditor (open Standard???.rul, in Basic tab change rule name to STANDARD-INVISIBLE and disable Ghost checkmark, in Spawn tab enter -1 everywhere in the first column of Y Spawn Offset, save as StandardInvisible.rul, open NullpoMino.exe, options -> rule select -> STANDARD-INVISIBLE, start -> line race -> current rule). You won't see the active piece until you use softdrop or wait long enough for the gravity to pull it down (I suggest gravity = 1, G-Max = 256). Be warned, playing this way is not a funny experience but it may help you to learn faster which keys to press to get a piece to a certain spot and it may help you focus on the next piece(s).
