1 ppm is pretty easy to detect.
How about something like a counter and a PC. Use the crystal in the counter
as a 3rd opinion. You don't care if the crystal is off a bit. You are just
assuming it is reasonably stable.
Of course, now you have added a PC to the system.
These are my opinions, not necessarily my employer's. I hate spam.
