In a generic sense, I truly disagree with this statement, my replenished Xtol has been absolutely dependable at 1-2 films per week even after skipping a month.
I believe that replenishment's dependability is driven by averaging out mixing errors.
I keep 1.75 liters of working solution. My largest developing tank holds a liter so I never use my whole reserve.
I replenish at 70ml per film, this number is easy to measure accurately and even if I miss by 5% on one replenishment (which at 3.5ml would qualify as a truly sloppy error using a 100ml measure), the net effect is negligible.
The smaller the amount of concentrate the harder it is to measure accurately.
I am not saying that small batches can't be done well with the likes of HC-110 and Rodinal but, assuming good working and storage practices, there is nothing about one-shot processes that makes them intrinsically more dependable than replenishment.
