Now I just have to decide how many more rolls of film I can use the 16 oz of diluted solution for. Ilford says 33 oz can stretch to develop 10 rolls of 135. That roughly comes to 2.5 batches of 4 rolls per batch. With 16 oz I can do 2 rolls per batch, but am not sure how far to stretch it?
Just one thing, Developers oxidise and water has a lot of oygen in it. So the life of developer once you mix it to working strength tends to be very short so don't push your luck. Like the others here, I use one shot and discard it but if you are doing two or three uses in one session then you should be OK.
It's activity will reduce with each use so again check what the adjustment should be from the datasheet. 24 hours is OK for some developers and not for others. Developer tends to go brown when it oxidises but not all of them and I'm not sure about DD-X.
You'll soon find out
