[Sir Folds A Lot]

PSR sounds like M in Harrington on hold em. I think it is a Sklansky concept, but I haven't read his book yet. Harrington explains M as the amount of your stack compared with the blinds and antes added up. If the blinds are 100/200 and $25 antes at a 5 handed table and your stack is 3000, you have an M of 8. 375/3000=8 It basically tells you how many orbits you will survive until you are blinded out. When your M is low, Harrington recommends getting all your money in when you have a decent hand like TPTK.

I don't even know how to fold mid pair, so I can't tell you what you should do with TPTK.
