wowwwwwww.... how are people this unaware of what is going on when people do tricks with the amount of existing slow motion footage out there...
Here is a random video of some guy doing a misty 9
watch carefully... he spins 90 degrees and a half a flip to get into his off axis position that he is spinning in... and then from that point you can clearly see 720 degrees of rotation, two full spins, at that same angle before finishing the last half of the flip and the final 90 degrees to end up backwards.
Now i see where you're coming from with a flip equals a 360 when it comes to rodeos and flatspins... but this flip only counts as 360 degrees of rotation because you are doing it at an angle which makes it so your flip is going around the same axis you spin around( a rodeo the flip is similar to a sideways backflip and a flat spin the flip is closer to a lincoln with your back flat against the ground)
so guess what going inverted does not equal an extra 360 degrees of rotation so here's a little key
tricks flips count as extra spins in- flat spin, rodeo
tricks they don't count as extra spins in(because these tricks simply cause you to go inverted as a result of the off axis rotation rather than truly having a flip in them)- misty, d spin, cork, back full, branny, flat360/whackflip( if you watch carefully this trick greatly varies from a standard flat 5 and you can clearly see 360 degrees of standard rotation in it... if the 360 degrees aren't there they are just doing an egg roll or in other words a slightly tilted backflip) any flip trick with a spin in which the axis of rotation does not stray from a standard 360 type spin combined with a standard backflip type flip.
underflips and tricks like this are grey area because there is such variation on how they are thrown, but typically according to how i've learned these tricks they are 90 degree rotation a flip and then 90 degree rotation
so yeaaaaaa that's that
