No, I've heard of those non-contact methods

In this case I used a counter with a x10 probe, and measured it
at 19.66350-ish. Aw, stink bro'. I wasn't sure the probe hadn't
loaded the pin (although loading would have made it run slow, not
fast) so I ran the unit for a day, and it did actually work out to
what I'd measured

So, even if I could trust the measurements I make when trimming,
I've gone off trimming these units anyway

I can compensate for a frequency error in s/w, but 22pFs would
be close enough to not do any long-term physical damge ?
