Yes, but the only way you get a number not divisible by 15 is if, for some number of given drivers, it must have been correct for some trips but incorrect for others. I would not consider those drivers to be "successfully identified". Remember, the goal of this is to isolate individual drivers.

No, it could have been inconclusive for the other 10% of the trips, simply stating, "Insufficient data for meaningful answer". So 90% of the time it said, "Oh, this must be DrScump" and the other 10% of the time it said, "I don't know who this is yet, let me keep analyzing the braking patterns"

EDIT: Which is different than the way I stated it in my initial comment. Your reply helped me realize that.

But this is a binary problem (they did or did not ID the driver); "inconclusive" = did not.

Yes, 10% of the time. The other 90% it did. So.. 90%. Not being snarky or passive aggressive, I just don't understand the issue you're having with that statistic.
