There is no "truth".
It all depends on the male, the females, and whether or not you as a breeder have done your job.
You have to remember, these are animals, not DVD players ... you can't "program" them ... they do what they want ... all you can do is put them in the right direction.
Most important thing to remember ... males will breed themselves to death if you let them ... I know a guy that bred a very young $18,000.00 snake to 15 females a couple of years ago ... 12 became gravid ... and the $18K snake died.
Small, young males should only be bred to a small number of snakes ... larger, stronger males will do well with more ... You really have to listen to your animals and let them guide you. Every year I start off with a "base plan" and then let it evolve over the course of the breeding season as I observe how well (or not well) the males are breeding and assess their overall health.
