Thinking of trying out wendlers 531 quick question

[Bruce44]

I tried to search if anyone else has asked this question but I couldn't find anything so please forgive me. After week 4 when you deload and start over again, how are you supposed to find your new numbers? I typed my numbers into an online calculator but it only goes to deload week. Do I just add 5 more lbs to the routine, or do I actually have to try to find my 1 rep max for all the lifts? Thanks.
I'm just doing a comparison right now to madcows to see if I would like this program better so I don't want to spend any money just yet.

Edit: Nvm guys sorry I just found it. I just didn't know what to type in to the search bar. Mods if you could delete please?

You didn't say what the answer was that you found, so I'm going to answer you.

Add 5 lbs to the original projected max (or 10 for squat/dead. I would still use 5) and then redo your percentages from that number.
You can re-calculate your projected max anytime you want, but I wouldn't make it a habit. The program is intended to be a prolonged steady progression.
