Well, you noted in post #6 that it was a “sub only” graph. I assume that means you did not have the receiver in the signal chain at the time. The receiver can’t “do its job” unless it’s in the signal chain... Using the CD or AUX input will put the receiver in the signal chain. 
If you’re referring to the graph axis, 200 Hz is fine.
Typically recommend graphing the sub first, then adding the mains, but that’s if you’re equalizing the sub. Since you’re not doing that yet, it doesn’t matter.

Sorry, I meant that i was "attempting" to measure the sub only. I hooked up the sound card to the receiver's CD input. Your observation of no drop off after around 80hz means 1.) my mains were in the mix when "attempting" to measure only the sub, 2.) i did something wrong. I think it's both.
Question: if i retest, unplug my mains, reverify speakers are set to small and crossover 80hz on the reciever, i should get roll off at/near 80hz? If i don't, then is my problem with my sound card and/or REW settings, or bad receiver?
