More confusions come as long as that swJumpad was the best stuff for A.I. and Human jumping as long as you don't mess setup with KICKER around. Also you are able to control a bit your "landing". I was playing maps from 300K (open your eyes there) where swJumpad is used (Wootious map included) and if you play normally (RESPECTING 4 TOUCHERS rule by Unreal Engine) stuff is pretty better than any sort of mess supposed to do A.I. jumping but doing nothing. Aside feel free to combine LE-LC-LE if you can manage that. I prefer to leave alone good stuff because a single fail from 200 or whatever might be caused by a SHOOT changing Velocity or whatever factor (nearby KICKER might screw up) because Kicker has nothing to do with navigation, but is bugging A.I. properly. I was falling down in map which I privately sent at Terraniux because those clowns XAN_A and XAN_B were against me in the same team hitting me in air and bugging my velocity ON Y AXIS

. When they somehow were busy to respawn behind the rocks I felt more comfortable at any landing. Else sWJumpad which I'm using in the middle is doing the job properly even if see a LOG warning (not ScriptWarning) because angle is too closer to 90 degrees, but I still can reach in upper location ( And BOTS too ). In the Level pathed correctly I see a good difficulty for keeping you warmed up else I have a few risks to sleep on keyboard.
As for pressing <walk> while flying, I did not test that, but if things goes nasty the same things might occurs at kicker too...
Edit: A little test Looks like walk and back pressed shortly might screw Y velocity and you might fall at middle of road. Who need WALK Back in that moment ??
