Key force specifications for the Model M?

I'd actually prefer older specs from the IBM-era boards, but newer specs will work as well.

I do know that the M15's spec is 65g +/- 10g.

It would be nice to find a force graph or datasheet for the buckling spring.
This site found the activation force of a 92G7454 to be 80 cN.

Well, that's 70 grams, although that's not necessarily correct for an M.
