If anyone needs help with reducing their times, practicing routes, etc. please put your query in here and me or others will help.

on general movement. Is it better to do one large swing or a bunch of small quick swings.

It's really situational, and I'm still uncertain of the BEST ways to gain speed. Best advice I can give is that personally I try every combination of different swings to find faster routing, and then apply whatever gets me the fastest times. But small swings tend to be better for quick angle changes, and large swings are great for building lots of speed from a swing point. Like how in level 5 we swing round the back and use one large swing on the chains on the wall to build a lot of upwards momentum, and how in level 2 you can use little swings to carefully manoeuvre through the trees.
