Deload on BBB 3 Month Challenge

Hey,

Maybe this is written somewhere but i cant find it.
This is a 3months challenge, which implies that Jim recommends a deload week every 4 week, but on most other BBB programs he outlines deloadrecommendations every 7 week, so its x5 week, x3 week, x1 week, x5 week, x3 week, x1 week, deload…

The 531 sets/reps arent taken beyond the prescribed numbers, which makes me think deloading every 4 week is kinda over the top? Im not questioning if thats what it sounds like, but whats recommended?

Every 4 weeks. Just like the book says.
