Let's not get too excited over that video, or that the numbers are varying by as much as they are. Different brands/types of dyno's, run by different operators using different correction factors can explain most if not all of it. Dynojets are a bit notorious for putting up big numbers and sweep tests (full gas from low to high revs) are not the most accurate way to do it, although that's what you see all the time in vids. I'd only get worried if I saw a test that was run on the same dyno on the same day by the same operator showing a Pani running low HP relative to say, a Fireblade or an R1 when comparo time comes. It "should" come in somewhere between the ZX10 and the S1000rr, so if it does then all is right with the world, regardless of the absolute numbers the particular dyno spits out.
