Hi, late response but we're mainly active on the Discord server:
https://discord.gg/harddropThe Tetris scene has gotten to the point where even sub-60 isn't considered a fast or decent time. Sub 40 might seem unattainable for you right now, but if you keep with it that's what most members on Hard Drop would consider respectable.
Tips to consider:
Balanced control scheme between both hands that divide the work up evenly.
Using both rotation directions.
Don't rely too much on hold piece.
Stack flat in a way where there are a lot of options for your next pieces to fit.
