Thanks for the pushback on some of the data, I have only been putting this together in the last month or so and it is a lot of data to validate!
I just compared my data to the individual season schedules and I found 17 games missing, mostly on the NT side from seasons 24 and 46. This was updated and I believe Per-Ivar Kristiansen-Skjeveland numbers are accurate. One thing to note, my script only counts games played based on actual minutes in the game. I am guessing the BB site counts players rostered in their "games" metric.
Also, it appears seasons 7 and 8 have been purged from the site, I haven't been able to find any international data for those two seasons. There is also a U21 scrimmage from season 17 that will not load either because the site say the game is live, so with one exception, I was able to pull all the data since season 9.
