"Temperature spike" question, sort of, during breeding season...

[hungba]

I remember I read somewhere where someone said that he had a temperature spike during the cooling and caused his ball pythons to ovulate early or something like that, ultimately leading to failure to breed anything that year. I can't for the life of me find that post again, nor am I even sure it was from this forum.

This is my first year breeding, and I think that it is reasonable that I may make some mistakes. I did not have a "temperature spike" per se, but I have a habit whereby I have an empty tub in a rack where I put my snakes in when I change their tub newspaper and clean it out. I have kept doing that too with my cooled breeding snakes. I forgot that tub is HEATED. Same as usual 90F or so on the hot end which due to it being a smaller tub is 1/3 of the area.

Not all have been in there since breeding started, and those that have have been in there one or twice at most, and for no more than 2 to 4 minutes. I just put them in there, change the paper, wipe the tub and put them back. Will this cause a bad effect?

PS - Another question, now that I have done a little more research just now, I read that people are saying to never let any snake during breeding season come into contact with anything above 82F? But I was advised by two very big breeders to keep ambient temps at 75 - 77, and give a 12 hour a day hot spot of 85 or so?
