Everybody has their own methods, the methods are far less important than the results.
The best free advice is this :
Observe your snake. If it's spending all of it's time on the hot side, you're not hot enough. Same with the reverse.
*I will add identical hides to this as if one is "more secure" the snake, it will always pick that one regardless of temperature.
When your snake happily settles into a routine, you have it right.
My guy goes between his hides all the time. I will say that before and after eating, he spends more time on the hot side. But his big nap that normally comes between the feed and when he is ready to eat again, happens on the cool side mostly.
I think pride and thinking you know everything often gets in the way of simple observation.
