I would agree with Gene. I had to determine the front ratio of my 4wd and
was always coming out inaccurate until I performed the test on the ground
rolling.

This test has never produced reliable results for me. However do the same
test with all four wheels on the ground will always get a true ratio. This
will not be errored by slippage that can occur with one wheel off the ground
( excluding locked rearends). It's more accurate but not easier.
