Here's a formula that puts you in the correct range for Fuji's data sheet on Acros with full strength Xtol:
developing time in minutes = a * degrees Celsius ^ b
where a = 2148.484
and b = -1.872
---------------------------------
for dilutions of
1:1 multiply time by 1.3
1:2 multiply time by 1.6
1:3 multiply time by 1.9
These are based on Kodak's older recommendations for similar films at higher dilutions. This will get you close, but you'll need to test for your own conditions.
