Realizing a bot that generates more than 800 calls/min

Okay, so statistics sites operate within these limits? I actually expected them to be more accurate and able to get data more frequently via multiple tokens. I did read about token management but nobody was specific how it is done or what token management means.

What about user tokens, as far as I understand the documentation user tokens also have 800 calls/min. Is there any limit to users I am allowed to register for this purpose? And if not, why is there a limit on app tokens I can register?
