i guess my one data point is better than none, anyway i can easily check my d76 pH but unfortunately i didn't check it when first made so that wouldn't tell very much (i've seen our water here jump around from 5.5-6.7)(posted 8497 days ago)as for increasing activity, i should know soon... i just developed a couple rolls with some 4 month old d76 and this time i cooled it down to 20 oC so i can compare to past results, i can verify that 4 month old d76 at 24 oC is much more grainy with slightly more contrast than fresh d76 at 20 oC..... i'll be printing some of the 4 month/20 oC negs this week and i'll post comparisons
