I have reported no precision - my 100 MHz scope has
not been calibrated since I retired.

It doesn't take much precision to know that there's
something wrong when two measurements are a magnitude
apart or when someone asserts a 3 nS delay through
a 10 inch long slow-wave solenoid coil with a VF of
0.033. :-)
