Just for a different perspective, I do just the opposite in that case ... since it only takes a single lock for a female to become gravid, "good breeders" see the males less often ... that way I'm not (in my very humble and small opinion) burning the male out by breeding a girl that is very receptive and I can focus the males efforts on girls that are slower to come around.
It's also important to be able to recognize "courting" but not copulating vs. no interest at all. The difference between those behaviors help me key in to how often a female will see a male as well or whether I have to resort to "other means" to get the female to become receptive.
Lastly, being able to develop solid palpation skills (or investing in an ultra sound) is another great way of knowing how often a male should be paired with a given female (or more important, when he no longer needs to be paired with a given female).
The good news is that there are many many ways to breed these animals and be successful ... the way I do things is just what works for me, and it works very very well.Super kudos to everyone else out there figuring out what does and doesn't work for them ... that's 1/2 the fun of doing this stuff!!!
