How many times you can use say a gallon of developer to develop 4x6" plates, before the developer is exhausted?

sorry, I ImagON is developed in washing soda, or sodium carbonate or
soda ash, depending who's giving the instructions. 10g/litre.
Your probably referring to Toyo-plates or alike, here 38eur/A3 size, bit
too expensive for me :-(
ImagON was 28eur from Polymetaal, 30.5cm x 4.5m roll. And if you ruin
your plate, stronger alkali (household ammonia diluted) removes the
film. (And I've recycled my zinc plates couple of dozen of times by now).
But what a difference using Akua instead of Caligo Safe wash ink, much,
