What are you topping up the developer with? More developer? Kodak likely lists a number for square meters of paper per so much developer. Depending on how much you're topping up then you might be replenishing. Are you pre-washing?

With me I find the bigger issue isn't the number of prints so much but the amount of time since I mixed up the developer. I can get quite a bit more then the kit I'm using claims I should if I use the stuff quickly.
I just top it back with more developer -- just to keep the fluid amount right. I chuck it all and refresh based on how dark and icky it gets and blind intuition. I pre-rinse 30 seconds.
