The fit chart is primarily intended for use with the 9-series, but it can also serve as a good first crack at 7-series sizing. The 9-series front end system was designed to cover a similar range of bar centers that you can achieve with standard stem & spacer combinations...the major difference being a drive towards micro-adjustment at the armpad level vs via stem & spacer changes.
Within a given frame size, then, the 9-series stem boxes on the chart each cover 1/6th of that bar center range. For 7-series purposes, once you've highlighted your pad stack row and pad reach column (-s...remember to give yourself 10-15mm on either side owing to pad-level adjustment capability), note which intersections occur within a stem box and which frame size covers the most (if not all) of those intersections. This should point you in the right direction, and you can fine tune with stems and spacers.
Following that process and bouncing the rest of your contact point measurements against the other corresponding cells of the fit chart, you look pretty solidly Medium to me.
