It really makes no difference on or off-road if you run 4.10/4.10 or if you ran 4.10/4.11. In 2wd, it doesn't matter at all because the front axle is free-wheeling anyway. And in 4x4, the front and rear tires already rotate at different rpms whenever you make a left or right turn, or even drive around a curve because whenever you do either, your tires rotate faster than the rear tires do... there is more difference then than the little .01 difference in 4.10 vs. 4.11 ratio that makes them rotate at very slightly different rpms.
Plus off-road, the slight difference in f/r ratios is a 100% non-issue as the tires slip around on the low traction surfaces or, again, as you even turn left or right which exaggerates the f/r tire rpm differences.
The reason for the slightly different f/r ratios like 3.54/3.55, 3.73/3.74, 4.10/4.11 etc. is due to the different sizes of the ring gears in the front and rear axles. It costs the R&P too much $$$ to make them exactly alike when the ring gear diameters are different. Only the Rubicon with its matching f/r Dana 44 axles have exactly the same f/r axle ratios.
