Left+right at the same time is required to do ZZMT (charge timer for the MT doesn't get reset so long as a left or right direction is held with no neutral input). Requires a worn down / modified dpad.

If that's the case you may want to update the banned list on SRC for glitchless as shortboost is not specified as something banned.

So long as you aren't using any of the listed banned techniques in the rules, you can do sequence breaks.

Adam Save Skip and Early Ice Missiles (without using WBJ) are allowed as a result.

For early waterworks the goal is to land on the edge of the pipe while still out of bounds. Going too far right will put you back in bounds. The goal is to double jump on to the pipe out of bounds and then tail twirl off of it once you see dust from landing.

My best tip to you is to adjust your jump so you're further to the left. The area you can land is deceptively large compared to how it looks, so continue to adjust further left until you land on the pipe without clipping back out. Takes practice but once you know where you can land it'll become much more consistent.

Good luck!
