ah okay, no problem. there aren't really graphs specifically for midfat twins. there is one for what they call "everyday skis"(stuff like rossi b-squad and dynastar legend pro rider, but the 4frnt EHP is in there)
and a small "girl skis" category
i also found some better information on how the test was conducted and the data collected...
(from the posts of a guy named endre on the skibuilders forum - i think ran the tests)
"The y axis is stiffness, calculated from deflection of a 10cm span of the ski.
The results from the deflection test are in mm, then I divide the force
I use (25kg/249N) with the deflection of the ski (mm). this number
gives an indication of the stiffness of the ski. The stiffness varies
between 10-1000 N/mm, depending on where you measure. The middle of the
skis vary between 300-1000 N/mm, but in the diagram i put out here the
softest mid-part is around 450N (Goode) Of cource the middle of the ski
is not the most important part.
You can see three marks on the y-axis. the one at the bottom is
0N/mm, the one at the middle is 500N/mm, the one at the top is 1000N/mm
Here I got a scetch of the principle of the flextester, it can be
done really easy with cheap tools, you don't have to make a machine
like mine (would be cool if you did though, that would make us able to
communicate flex geometry)"
