Most crystals are +/- 0.005% tolerance or better at 20 degrees C.
0.005% over 70 minutes is about a quarter of a second.
You forgot the percent sign (an easy mistake). It would actually be a
bit
over 0.002 seconds.
Hmm
calculator says:
0.005/100 * 70 * 60 = 0.21
or
70*60 = 4200
4200/100 = 42
42 * 0.005 = 0.210
where did I go wrong?
