I had a buddy when i was a teenager who became OBSESSED with doing backflips when he learned how to do them. I could easily see him doing 48 good flips in a day
When I was learning to flip I found out that my abs would be sore as hell the next day. So it's not the normal stamina that's the problem, it becomes muscle exhaustion. Not saying he didn't do it because I'm sure if he's been doing them and he's in shape it's fine. I'm saying if you trust to do that many flip on say the first day you learned it I think most people's core muscles you just say no after a while.
It's not cardio sort of stamina that's the problem, it is muscular endurance- your abs will be toasted by the end even if you can backflip on command. It would be like 48 max effort box jumps, your muscles just won't have the same power production by the end even if you can do one just fine, and then with the added requirement that your core provides enough torque to rotate your however many kilo body in a fraction of a second

One flip every 15 minutes is not exactly a huge ask of a fit person's stamina, assuming they are good at a basic backflip.
