Cooling? help me out guys

ive been doing quite a bit of research on breeding ball pythons because i hope to breed my pair of ghosts next year, and ive hit just one fork in the road. Which is cooling, i gotta good understanding of it just the minor details i need help with. im wondering do you guys gradually lower temps at night (day by day or week by week)till u get to the point you can't go any lower and its time to warm up? or just lower the hot spot and the cool spot a couple degrees until its time to warm up the temps back to normal? ive also heard cooling isnt necassary, does that mean if you introduce a male to a female there's a chance they'll copulate?

This may help you http://www.ballpython.ca/gallery/breeding.html

actually thats the page i was reading that inspired this thread cause ive read it many times, quoting it "In October we lower our temps at night. The hot spot goes down to 82 F and the cool end is 72 F" so it's only a night drop i get that part but do you lower it to same the temps every night until its time to warm up? id imagine you'd gradullay lower the temps like a degree or too every week and same for warming up... or am i just plain wrong someone plz clear this up, thx:)

Maybe this one is will explain better http://www.8ballpythons.com/journal/...ngcalendar.htm
