Okay, we need to get something cleared up.  Are we talking about sidecut or rocker?  The widest points of the ski don't necessarily have to line up dead perfect with the contact points of the bases.
The sidecut is not symmetrical, I think that was established, but for those uninformed it's multi-radius, which they call "Fivecut", I imagine it could be called "progressive sidecut", as in it gets progressively tighter, but who cares.
Most importantly though, it's only +/-1.5cm discrepancy measured semi-accurately with a tape measure.  Hopefully, the tip rocker will be longer.  Besides, we all ride forwards far most often, and so most skis will naturally break in more up front, making early rise....earlier.  If you're honestly worried about it, just relax.  You're "done with Line only buying on3p now" comment reaks of troll, hell maybe not, but I could care less, because everyone who's been reading the thread at least learned some more about the skis.  I'm glad I didn't turn out to be "embarrassing myself" all along.
