If your top set is 200 on the “5” week and you get the minimum reps or greater AND you feel like you can push yourself, you would add 5-10% (of the 200 lbs) to the top set (200) and do another set of 5, if you get that, add another 5-10% of the top set and do another set of 5. So on and so forth until you cannot get the 5 reps.
e.g. First joker set would be 200 + 5-10%, so 210-220 lbs
Second set would be 220-230 lbs, third set would be 230-240 lbs. All done for 5 reps if this is the “5” week.
On the 3 week, add 5-10% per joker set and do sets of 3.
Same for the 1 week, add 5-10% of the top set and do a rep. If you get that rep, add and keep going until you cannot get the rep.
I only go for joker singles regardless of which week I’m in IF (big IF) I feel like I can get them. I just like singles better. I am doing Beyond 1.3 currently and after my PR set for squats using my training max, I added 10% and did a single, then I added another 10% and did a single. Then I quit and did the 5x5x75%.
Sorry for the rehash of an earlier post, but sometimes seeing actual numbers helps some people (like me)
