Zercher Squat to Back Squat Ratio

Im doing westside program and rotating max effort squats every week I smashed my toe 3-4 weeks ago and I tested my back squat and got 535
Then on the past Monday this week I did zerchers and got 545 and could Have done more but stopped with out knee sleeves, how much could my back squat increase to What weight ratio

I found Zerchers improved my deadlift and did little for improving my squat numbers, although my squat felt more solid at the weight I was doing.

But CS you’re an animal man… I’m sure your experience will be different.

Thank you for your answer im going to try back squats on Monday to see if I improved
