I used a 15L replenished Xtol dip-and-dunk system with nitrogen burst agitation for a long time when working in a commercial lab, but never tried to do it for myself. Even if you make up 5L of Xtol and follow the re-use instructions, you need to use it quickly.
I tried replenished Xtol for small-scale development (less than ten films a week) but found a significant speed loss after a while. This is seldom mentioned by the exponents of replenishment and I figured it was probably due to the by-products of the development process. Is this speed loss to be expected or maybe a fault with my technique?
