Kodak Academy 200

[Photo-gear]

I have been give a roll of Kodak Academy 200 and did give it a try this last week-end. I was lucky enough to get across some interesting portraits taken on the street.
My question is the following. The time development given inside the box is 7,5 min with D-76 stock solution (20C). I could go ahead with this time but I wonder how much time would be necessary with a 1:1 solution. On the net, I have no such information.

Anybody have a suggestion? Should I try 11min at 20C?

This is not terribly scientific, but I would say 10.5 minutes, based on multiplying the stock solution time by 1.4x for a 1:1 dilution. This is just a rule of thumb a photo teacher gave me years ago for situations just like this. 11 minutes would not be *that* different.

Finally I went with 1,6X time for a dilution D-76 1:1.
Results are honest, so far.
