Pervertor Training Session Time/Program Transition

I’m pretty set on doing Pervertor for my next 5/3/1 cycle and am curious how long sessions will take. I know everyone’s different but if those of you with experience running it could share I’d appreciate it. I’m in decent shape and am planning to do the assistance work between sets of the main/supplemental work. The reason I’m asking is because I train early mornings before work and would like to avoid marathon training sessions if possible.

Also, do you just do a 7th week TM test between programs that use a different TM%? Currently running Limited Time w/Widowmakers and using a 90% TM, while pervertor calls for 85%.
