I think the total volume idea is more flawed than you realise. Pretty much everyone would be able to achieve greater volume, on any exercise, just by decreasing the weight, so your high rep caveat is covering up for quite a lot. This is true mathematically for an Epley style model for example.

I’m not sure this is true and it might be the opposite. Lactic acid will build up with light weight while trying to hit a volume number that will make it hard for people to finish.

I tried various combos of weight* reps, and in the end the optimum was somewhere in the middle because no matter how light the weight there was a limit for me at about ~150 reps.
In my case, the curve would be: total volume increases quickly initially at you go from max weight/1 rep to something like 20/30 reps, then something of a plateau as things equalise, then it goes down again as you reach the max reps threshold.
