Not sure what the "threshold" is, but the general answer is NO. Certs have been pulled from riders that publically bragged about doing stupid stuff//speed. And someone that attempted one on the Tail of the Dragon, which has too low of a speed limit to do it legally had it denied.
In a nutshell, Yes, the verification teams do look at this stuff. Keep in mind that large areas in the Western US have 80 mph speed limits and certain areas in TX have 85 mph limits, so calculated average depends on your route/location.
