I pair mine up on a 3 and 3 schedule. I put them together for 3 days, and separate for 3 days. Sometimes its off by a few days like 4 days together and 7 days apart, but for the most part, it is 3 and 3.
Also, I do not cool, so I don't ever have to bring them up to normal temp. The natural dip in temperature during the Fall and Winter here is enough of a cool for me. I've already seen 2 locks from the same female. I'm hoping she goes this year! *fingers crossed*
