A little experiment

I'm sure we have all seen evidence one way or another pertaining to the effectiveness of draw/non draw and curved/non-curved blades. I'd like to do a little experiment to find out how much these are actually affecting a blades motion during a cut. I know people have measured it before, but all I ever see are their conclusions, so I have no idea if they initial data is accurate enough to support them.

I however have a simple experiment. Take out your handy dandy protractor and measure the angle of the scratches on your blades (Angles off of perpendicular to the blade, the smaller of the two you could measure). This will indicate the blade's path through the object it is cutting. If there is little change amongst the different styles of blade it serves as some good quantitative starting point. (Aside from the small sample size.)

If as many people as possible could reply it would be greatly appreciated. Also include a general description of your experience (new, medium, experienced) and estimate as best as possible how much draw you apply to your cuts. The last two aren't as scientific, but they will probably help in analysis of the results.

EDIT: And length of scratches from the hilt.

For example, mine:

Curved (katana)
20-23 degrees
22-25" from hilt
beginner
no draw


Straight (ninja-to)
10 degrees
20" from hilt
beginner
no draw
