Temp of snake?

[Neilp]

I learned over twenty years ago with boas, sometimes it’s better on the cool side (Jeff Ronne). I have no need for temps in excess of 86, let alone 92 for a ball python. Juveniles even more so. Just my personal opinion. I imagine a ball python would be moving mighty fast at a body temp of 92 degrees.

Hi im new to snakes but if you are correct why does everyone say basking spot of 90 minimum?
Im not saying you are wrong its just you're the only person ive noticed say that. And im still learning new things everyday and dont want my snake th suffer if im wrong. Surely the idea of the basking area is that it warms up then moves away to a lower temperature area?
