Ben Johnson Squat 1rm?

Just looked at this example of his program…

…and only the first 2 weeks out of 7 are 3 x 10, all other weeks are 3 x 5, and 10 out of 24 workouts are at least to 85% of 1RM. There is only one light day (<70%) which would equate to a 13RM load. How do you call this a system based on 3 x 10 at 13RM when there is only one day out of 24 close to this?

I’m not a westside boy, although I do recognize that there happen to be an unusual population of elite lifters at that particular gym and that most of the guys I run into at powerlifting meets who are of any consequence take at least a portion of their training from westside principles.

I’d like to see some strength athletes that train exclusivey in the sub 70% of 1RM. I mean people pushing or pulling big numbers who got there doing 3 x 10 x 13RM without ever doing heavier loads.
