Mike, I meant once mixed with water, I did not mean to imply that the concentrate was bad. What I did was develop one step wedge, go out have a cig, check APUG, etc. Come back and do the other step wedge, overall the 1+25 solution sat about 1 hour while I was doing all the step wedges. All 4 negatives resulted in about the same densities...weird!
I have to do 1+25 for pt/pd, if I could get away with 1+50 I would but dont want to spend 30 minutes developing a sheet..
