e1RM for Lever Row in Powerbuilding I

I’m on week 6 of Powerbuilding I and noticed that Exercise 3 on Day 2 is the Lever Row at 70%e1RM followed by 63%e1RM. Unless I missed it somewhere earlier in the template, this is the first time I’ve seen the Lever Row so what should I be using as my e1RM?

Thanks!

Use a load you think you could get ~ 12-15 reps @ RPE 10 at. That’s about 70%.
