@Query: I noticed the Toe Picks don't line up and it's off too much for it to be attributed to the asymmetric cutting of the pick clusters.
The blade is also being moved & rocked back and forth as the video is panning along the length of it, so at different points it looks like as if the blade is at a different position relative to the tracing.
Going L->R, the blade looks almost on top of the tracing. R->L the tracing looks like it's 1-1.5MM above the blade. L->R the blade looks like it's jutting up above the tracing. So, the blade is moving throughout the video, on top of the pick cluster not being lined up. It's unusable for actually comparing the profiles. This is probably due to the same person holding the blade recording the video - I am not saying it's being intentionally done.
Personally, I don't like JW/MK blades and I've been pretty up front that I would buy a Paramount Blade over theirs unless I got the JW/MK blade for like $150 less than a Paramount 420SS. That's the only reason why I got JW P99s. Without that discount, I would have bought from Paramount, because I dislike the wide tolerances that JW/MK uses when manufacturing their blades.
I will say that at the beginning of the video, I can clearly see the front rocker of the blade on the Right of the Frame is more flat than that of the blade on the Left of the frame, and this would be very noticeable when skating on the blades - for me. I would return them for that reason alone. Differences towards the back of the blade are something I highly doubt I would notice at all, frankly. Even if I measured and saw anything back there (in isolation/barring any other issues), I would likely ignore it. It's totally possible that observation is just a visual effect from the difference in angle and distance from the camera, though.
