You would be able to tell if your clutch slipped 1/10th of a rotation by looking at the tachometer? We are talking about less than 1/100th of a second at 2000 rpm.
That is 2000 revolutions per minute, 33.33 revs/sec, 3.33...3 revs/10th sec, .3333 revs/100th sec, and so on.

I would say you are correct if you define slip as any relative motion whatsoever. The clutch "slips" just as your car "slips" while parked in a parking lot. After all, it is only friction that is keeping it from moving.
A properly functioning clutch would probably only slip your 1/10th of a rotation over the lifetime of the vehicle. Again, it would be like measuring how far your car has moved since you parked it. Or put another way, how far does your car move when you apply the brakes fully? The friction of the brake is the only thing preventing the car from moving.
I bought a Subaru Legacy that had a barely perceptible slip when mashing on the throttle. Within a month, that small slip caused it to wear very rapidly and then completely fail to move the vehicle with even the slightest amount of throttle.
I hate to say it, but I'd say it was an incorrect statement on your part. It would be like me appearing in court to defend myself against an assault charge and my defense being "my fist never actually hit the mans face; the electrons in my hand just got close enough that they violently repelled the electrons in his jaw".
