CFSB
Deadlifts
Round 2, Week 2

5 x 105.5kg
5 x 107.5kg
5 x 110kg

I'm claiming 5 x 110kg as a CF PB (ie ignoring pre-CF lifts). Last June I managed 3 x 110kg and I'm sure my form wasn't as good as I'm hitting now.

15 x 80kg
Not sure what I was supposed to do here.
I chose 80kg last week because the windows was 15-20 reps. This week the upper end of the window (12-15 reps) was my limit last week. Should I have gone up? By how much?

Someone move Ramona closer so I can do this stuff there and not have to guess so much.
