So, if someone could enlighten me, how are the ridership counts taken and how far off could the estimates be and could it be off?

Ridership is counted via sensors in the train doorways, not via sales of tickets and passes. Also, Diamondbacks attendees do not ride for free. It is only for events at the Talking Stick Resort Arena that an event ticket is also a rail ticket.
