fuji acros 100 / d-76 1:3 developing time?

[temujin]

i want to try out fuji acros 100, i've heard great things about it, but the fuji web site only lists developing times for stock and 1:1 dilutions of d-76. does anyone know the developing time for a 1:3 dilution of d-76? i will start out shooting at box speed. thanks.

Unblinking Eye lists your times using D-76H, which I guess is D-76 with some borax in it.

No, both the original Kodak D76 formula and D76H contain borax.

D76H omits hydroquinone, and increases metol from 2.0gm to 2.5 gm

The reason the Fuji does not list a development time for the 1:3 dilution is probably because it is rather long. Development time is roughly proportional to dilution so I would try 2X the 1:1 time. But it is always a good idea to test before risking irreplaceable negatives.
