I might have a slight time saver for the new any% run. In the pillar room in LN, it might be possible to blue suit through enough of the pillars to obsolete the spark method.

Here is a method I made which gets through most of the pillars and uses a PB to clear the last 2. Unfortunately the PB does not clear the 'half' pillar at the end which means that a super short charge cannot be performed there.
If... someone can manage to do the CWJ with a higher speed, you could walljump off the second pillar instead of the first which would put samus far enough into the room that a PB would clear the 'half' pillar also.
This method would be much faster than the spark method (no cooldown, and no need to reverse direction to charge another spark). It also saves a huge amount of energy, which is vital for the any% route.
ot - I am also thinking of a possibility for an entirely new any% route, but I need to figure out a few more kinks before it is feasible.
