Testing OEM stuff, especially old examples, is tricky. Its difficult to find old shocks with very few miles on them, so we do the best we can and take into consideration that the numbers probably reflect some wear and tear.
I will take a look at those numbers you have gathered and see if they correlate to anything we've found on the dyno, but off hand I don't see any rhyme or reason there. Some of the companies use truly bizarre formulas for those types of things. You could look at the numbers for days and not figure out what they mean without seeing the formula, and even then, they often base it on irrelevant figures.
