Scor-Pal Scor-Buddy Eighths Mini Scoring Board 9"x7.5" Imperial, Multi

Hi Scor-Pal, it says this one is the 106 model with the imperial system, but the picture is of the cm model. Could you confirm this is in inches?

Are the marks and groves accurate? scor-pal has some bad reviews of not being accurate. ex: scoring 11" at the 5.5 leaves one edge slightly longer.

Why does the description say " Product description Thin, metal die to use in most leading die cut machines to cut paper and cardstock..."?

Does the score-pal create better/crisper score lines than ez or martha stewart version?
