Since I am new at this myself I can only tell you what I did.
I didn't cool at all I tried and due to my rooms RH% I had 2 RI creep up on me and decided not to cool. I started pairing on Thanksgiving Day and didn't see my first lock till Janurary. Could cooling have helped speed things up? Maybe, but it wasn't worth risking a bad RI in a gravid female for me to rush things. I started watching the barometric pressure in my room. When the pressure would drop I would pair them up and BOOM! I was getting locks left and right it was great.

cheers
