Testing crystals

[Crackle]

My crystals arrived today. I have tested them all and most seemed to work, and some were even working on the marked frequency.
The results have been put into a table and the results can be seen below.
Most results were either a factor 2.99 so the marked frequency was a low harmonic of the fundamental
Some came up as the test frequency was about the same as the marked frequency 1.0 or 0.99.
But with the last 10 the marked frequency was a high 3rd harmonic of the fundamental.
There are 11 crystals which the 1/3rd harmonic falls within the MW but none are a factor of 9.
   
Is my analysis correct?

Thanks
Mike
