Yes.
I assume you mean 200fpm. It is very challenging when you are very draggy. For contrast, dolphins do 200 fpm when they are sleeping. So, the level of challenge for a particular speed is very dependent on the total drag of the system.
I'm working on an article regarding all of this. I'll link it to a thread in the "basic scuba discussions" section when it is ready.
Yes fpm.
Let me know when you approach the drag coefficient of a cetacean.
