Fork oil measurement?

Oooh, you sound a bit sensitive, I thought skin was a bit thicker north of the border. 
You've clearly taken offence where none was intended, so apologies.
To take your points though -
Why would the calliper mount affect the oil capacity if it was solid ? Especially if the other side has no mount.
As the only external visible difference is the caliper mount, it would be reasonable and plausible to suggest that the mounting, solid or hollow has in some way affected the capacity. It may not be correct, but it is reasonable and plausible to suggest it. I presented it as a guess, as I simply didn't know.
All I did was disagree with you guess and offer a more plausible technical explanation.
My comment was that I had seen no reference to having compression and rebound damping in any test, any website or the handbook. So your suggestion is as reasonable and plausible as mine, because neither of us have anything concrete to back it up.
"It was mainly Marzochhi forks that had that feature" ?
The first bike I owned that had rebound and compression damping in each leg was a Moto Guzzi V11 Sport, and they made a fuss about it at the time as it was a new feature for them. They quietly dropped it on later 1200 Sport models, though the forks were still made by Marzochhi.
The next bike I was aware of having Marzochhi with this feature was the BMW HP2 Enduro. A search on UKGS'er will find pages of discussion about knocking forks, with some even going to the expense of converting to WP forks after struggling with post warranty claims. When BMW then launched the HP2 Megamoto, it retained Marzochhi forks, but went back to conventional damping. I've seen no reports of any Megamoto having problems, and I'm on my second Megamoto, so do keep up with the HP2 forums.
The other question I would ask is, Why would a fork leg without compression damping wear bushes ?
BMW were reluctant to deal with the problem and never admit there is a problem unless they have to. But, the theory was that when used hard the leg with just the rebound damping was taking the hit harder than the leg which had the additional support of compression damping absorbing some of the hit. It certainly seemed plausible to me.
WP Suspension are doing it currently and are as good if not better than Ohlins. The theory being a fork with one thing to take cars of has an easier time and can do it's job without compromise. The spring does the preload.
I wasn't aware WP were now doing this, and it will be interesting to see how it fares over time given that KTM are the parent company, and whose off roaders will certainly give it a tough time.
I've owned a few KT's and CCM's with WP and also had it aftermarket fitted to a couple of bikes and it's undoubtedly good. But, I wouldn't say it's as good as or better than the Ohlins equipped bikes I've owned. We've all got different expectations of suspension though so each to his own.
No need to start flexing your muscles and trying to prove your technical prowess with guesses.
As said at the start, no offence was / is intened. This is simply a discussion forum, and every guess (mine or yours) has some merit until corrected by the facts, which neither of us have at this point.
