Total Visits - How does it work?

I am trying to understand the value that is presented in the Total Visits field. What I am seeing: 1) a Customer has 5 orders 2) this Customer has 7 total visits 3) the field does not increment on a cancelled transaction 4) the field does increment on a quote 5) the field does increment on a "payment on account" 6) the field does increment on a work order.

Is there anything I am missing - the numbers do not seem to completely tie out (but it isn't the easiest thing to verify...!)
