For years, Ford specs have called out 3.54 and 3.55 on the same truck. Same for 4.09 and 4.10 and other combinations. You're OK with such a small delta when driving in low traction situations. 1/4 of 1% has got to be less than tire-to-tire variability and it's way less than the front/rear difference in driveshaft RPM while turning left or right.
