Have significant difference in up and download speeds from one AP to another...3.56 vs 73.35 for down and 2.54 vs 68.83mps. Is this normal for such wide variations in wi-fi speed?

Assuming you're using an Internet speed test, there are too many factors involved to consider it a valid test of wifi throughput. You'd be better served looking at client metrics like RSSI, Tx rate, or SNR.

Having said that, perhaps there is considerable contention on a particular channel as a result of co-channel interference or interference from other electronic devices, like microwaves, etc. These particularly affect 2.4 GHz connections. You may also want to look at the layer two connectivity between the questionable AP and its upstream switch, e.g. duplex mismatches, CRCs or other errors.

I'm having trouble parsing your question. Do you mean the difference between up/down or the difference between those 2 APs (which BJ addressed). Difference in up/down is because that's how most broadband technologies work - they are highly asymmetric. You would only get equal values with a dedicated line type circuit (this often throws people off w point to point VPN connections as well, where "throughput is low" because of the asymmetric connection at both locations)

Those results look like differences in the RF interference field. Have you looked at this article:
