tl;dr: don't be moving or crashing when you hit 1

if you start a spark by hitting jump (B on the input display), and nothing else, here are the rough timings:
if you hit jump at:
- 67 and above (maybe 66): at risk of getting stuck, and softlocked if you do not have x-ray
- 65 to 30: you will skip the crouching cutscene after you hit 1, and you can go on your merry way faster
- 29 and below: you will not skip the crouching cutscene, but you will gain a bluesuit (and have a free speed zeb skip lol)
