PR days...How do you set these up?

[AZK]

In a few weeks I'll be nearing the end of a haphazard 5x5 program. I plan on using the MW of thanksgiving for personal record days and then resting the rest of the week and starting up a 5x5 with new totals after the holiday, or more likely, switching to CF for a month until winterbreak, taking the break off, and hitting the 5x5 hard in January...so how do you go about doing PR lifts to see where you at?

Sets of 5,3,3,1,1? Do you keep going if you think you can do more? Is there a more logical way? I'm looking to do PRs for standing press, bench press, squat, dl, and weighted pull ups. Thanks.

I was thinking off the top of my head of having Monday's PR as pull up, bench, squat and Wednesday's as standing press and DL...
