My friend believe that bio do not exist and are made up. He says anything beyond Rodeo 7 is just called Bio, however it doesn't really exist. If someone attempt or does a bio its automatically a rodeo not a bio. He says that CR Johnson wasnt doing a bio, but a rodeo.
I say that rodeos beyond 7, are rodeos over a 7 look like a rodeo 5 with straight spinning. Rodeo are a more backward spinning rotation, while bio is more foreward rotation toward misty. And bios exist.

cork is spinning "backwards" like throw you shoulder down and back. your feet dont ever go above your head. bio is the opposite. you spin forwards. so if you cork and throw you left shoulder back, you bio and throw is forward and down. rodeo is thrown back but your feet go above your head. misty is the opposite but forward. definitely.
Just to jump in, I would say that I have found bio to be set the same as a rodeo, except without the roll over the shoulder and instead just the rotation....my personal experience.Everyone seems to have a slightly different way of setting and performing their tricks, Rowens definition has it sorted though.
if you look at old footy, you can see an important difference between the two in big spins. for a bio, the big dip comes after the first 360, whereas for a rodeo, the big dip is right off the lip, and the spin flattens out after that.
Any rodeo past a 9 is pretty much bio in terms of what the actually definition of each trick is. However there is a pretty clear difference between how each trick is set, so people just call the trick how it was original set. So that's why its called a rodeo 10 even though it technically looks like a bio 10; because the skier set it as if they would in any normal rodeo spin but just spun so much that they did not go inverted enough to become a "true rodeo".
