Thank you for recognizing that I am not trying to be a jerk.
There actually are calculations that can determine with a reasonable level of accuracy how many reps you can bench at one weight compared to another weight based on the number of reps at that first weight.
People use them all the time to determine how many reps they should be doing at various percentages of the one rep max.
It is one way to test how close to failure you are getting, which is one of the more important factors in muscle and strength growth.
The attached image is the results from the calculator you can find at https://strengthlevel.com/one-rep-max-calculator
It is based on your 5 reps at 225 lbs and it appears I was being generous at the 20 reps of 175lbs.
My thought is that you might also have been able to do more than 5 reps, but did not push all the way to failure, in which case you might have been able to get closer to 35 reps at 175lbs
Unfortunately, it appears that you never tried to see how many reps you could have done at that time at your body weight so we can't test this in the best manner.
