In addition, supports will usually have higher armor than ad carries through early game (and often late) since running armor marks and seals (as opposed to just seals) is fairly standard for most of them, so your repeated references to them as lower armor targets are slightly baffling. Average armor values seem a little overstated, but not hugely. And it would be much more informative if the graphs noted the percentage change in damage from runes instead of raw numbers (and then used a constant scale from graph to graph), as the relative improvement is the important thing here.
But overall not bad, I guess.
