Without my stethoscope, I'd venture to guess that events like these are well in the Agresti-Coull confidence interval, given the ranges and number of candidates tested.

It would be cool if you'd find another factor for M7508981 or M9100919. That would be cool...
The event is not so common because all 3 prime factors must be greater than 3*1018. This lower bound is being improved by TJAOI, so in the future this event will be even more difficult.
