Dropped it by 5mm. Define jacking on the power. Is that preferable to jacking off the power? This may be why I noticed slightly more rubbing on the chain, you are a hero.
Jacking on the power is the opposite of squatting on it. Going to quit now before this gets out of umm, hand... Never mind!
OK, that made me dizzy, and then I ran it through Google Translator and got a BSOD.
As far as rear ride height (and riding position resulting from it, to keep somewhat on topic) goes, rotating the eccentric so that the axle moves further down works the same as adjusting the shock length longer. It moves the wheel down and further away from the tail, and increases the effective swingarm angle relative to the ground. Of course since the wheel sits on the ground in use, the equal/opposite reaction is that the tail goes up, rotating the bike forward at the front tire contact patch. Sort of like bronch's moving his seat and pegs up did for his body.
For the bike, it increases the rear suspension's tendency to stiffen under acceleration (jacking or anti-squat), raises the CG a bit, increases front weight transfer under braking, steepens the steering head angle and reduces trail. Rotating the eccentric the other way, such that the axle moves up, automagically has the opposite effect.
But, since we're rotating it to get proper chain tension and not for ride height, we have to counteract the result with shock length changes. So - if you measure ride height at X and after rotating the eccentric it's X +5mm, then you need to shorten your shock half that much to get back to where you were since the rear suspension has a 2:1 motion ratio. Or you can just say F it and ride it as is, which no doubt most do!
Also, would the different seat configuration have an effect on how the cover goes back on? 
I can't go with Lightech. Trauma will never let me hear the end of it.
So, why do you want the bars back 5 degr and not up!
Skinny is not the issue; skinny is good. Heck I want the thing to be as skinny as a motocross bike. OR at least Bimota, with their DB7/8/Tesi, who are my benchmarks in that regard for sporbikes. The issue is all the different shapes and edges that don't give you anything to lock into, or for some get in the way. For instance with my scrawny bod, (5'8", or 173cm), the inside of my knees hit the fairing in front of where it's scalloped on the sides, so I have very little contact area to grab. Not an issue hanging off in a corner, but not so great for being able to hug the tank under braking, etc. Combine that issue with the stock slippery, down-angled seat and you have something that might be great to look at, but is a bit of an ergonomic mess.
George has got it; grippy race seat cut down and re-contoured to suit, with adjustable clip-ons and rearsets dialed in how you like them.
People tend to underestimate the importance of ergonomics, but getting yourself centered and comfortable (in the sporting, not luxurious sense), makes a very big difference in your riding. I'll shut up since that's a bit of a hot button for me but before I do, think about it. None of us would accept a bottom-feeder KIA econobox with a non-adjustable driving position, but most think it's absolutely fine on a top of the food-chain motorcycle. IMHO there's no excuse for it; heck even a plebian Gixxer 600 comes with adjustable rearsets. Shutting up now...
