HN39, interesting, but the question is how the speed/AoA varies with change in weight.
I think the "max L/D" term on your chart should be "L/D". There is only one point of "max L/D", which looks to be about 0.5 Mach, at 5.5° AoA. Not knowing what the altitude is for that chart, I would have thought that that AoA is far too high to be best range speed ie best L/D.

Reason: added "is for that chart"
