Fuji Acros, Xtol 1+1, 30 minutes, 20C. I get an SBR of 2.95, and a gradient of 1.19.

Step Tablet density, film density measured with blue channel

1.88, 1.24
2.02, 1.04
2.16, 0.84
2.30, 0.60
2.43, 0.45
2.59, 0.30
2.73, 0.20
2.87, 0.16
b+f, 0.09
SBR 3.6
average gamma 1.33

These are results for a paper scale of 1.45, for silver the SBR would be much lower.
