End of the day you are spinning a potentially flexible bowl, attached by flexible bits of rubber to a cast aluminium plate with lots of holes drilled in it, which may or may not have been dropped onto the floor to cause a few micro cracks in it...
How fast do you want it spinning?
I don't have a rev counter so do it by eye, have almost definitely exceeded the spec. but most likely applying wax not cutting.
Use the tailstock to reduce the risk, and use good judgement, and you should be fine, probably!
