[amsat-bb] Observations on tracking programs

I've noticed a bit of sneakiness tracking AO-91 with Nova. I find I'm several minutes off once or twice a year. The main symptom is a weak downlink from AO-91 since the antenna is aimed at a spot in the sky which is not on time.

What I've found is somehow Nova has 2 or 3 instances of AO-91 in the table where you choose the satellites to add to the tracking view. None of the other satellites have multiple instances. What I need to do is to select each instance of AO-91 and keep only the one that accurately matches the other resources you can compare with.
