You've made a few mistakes regarding Mario.

Of the 101, there's "Detective Conan: Marionette Symphony", which isn't a mario game, at 0.02 million, pulling down the average. Also included is SSX On Tour, which just had a Mario cameo, at 0.17 million, and NBA Street V3, also with a Mario cameo, at 0.29 million. It includes Drawn to Life (has "Marionette" in the Japanese name) at 0.77 million. Removing these incorrect attributions, the numbers change a little, to 97 titles total, with a total of 508.92 million, average per game of 5.25 million and an average per year of 16.42 million.

Strictly speaking, quite a few other titles shouldn't be counted, because Mario is a character found in multiple franchises - so DDR: Mario Mix, for instance, doesn't really qualify as a Mario franchise title - it's a spinoff. Alternatively, if you consider the IP to be what matters, then you're missing Luigi's Mansion, Super Princess Peach, most of the Yoshi games, Super Smash Bros, etc, etc.
