I have a loaded question

Not on a load cell dyno, (Mustang, etc.). As stated above it MEASURES torque and calculates hp from that. But an inertia dyno, (Dynojet, etc.) measures HP and calculates TQ like you said below.
Once again, two TOTALLY different tools using TOTALLY different methods.

So it's not actually measuring rear wheel torque it is simply calculating what it would be at the engine based on the data acquired to accelerate the drum.

i thought that my posting about how an engine overcomes the force needed to move the car by use of gearing would be a little more talked about than it is. i mean alot of ppl don't understand how that happens so now its clearified. the lession from that one posting is vast. like having a large diameter wheel puts more of a strain on the engine or how larger gears make moving the car more easier while reducing the top speed. maybe it should be reread by all.
