At any given speed or gear selected,the 4.10 rear will be spinning the engine faster. Why is that so hard to understand?

You're NOW entering a MPH shift into the "mix" - the thread I thought and you mentioned again a couple of times was referenced RPM and if the shift is at the same RPM regardless of the gear the RPM differential remains the same but MPH changes at the RPM being discussed as the result. Tire diameter and axle ratio affect MPH but the RPM drop/spread isn't affected.
The engine and transmission are directly related/connected BUT the rear axle and the tire dimensions skew the results to directly affect MPH.
In this post "ZRXMAX" was in error and "HOG" corrected it and mentioned the only way to alter:
