My stop is 1.5 oz of glacial acetic acid per gallon and I don't try to extend that. Because the solutions are becoming more exhausted, I use 200ml for the developer and bleach fix instead of the usual 100ml. The developer starts out the usual light beige color and becomes a dark blue as it is reused. After 20 8x10s it is almost black. That is where I stopped although I could probably go further since there was no change in either color balance or density.
Good to know - just curious, but why 2 prewets? And are you using the Jobo lift, or the magnetic covers?

Thanks
