Yeah it's only the giant dynasty program that adds up to more than 100% and that's just because otherwise you'd need to own every live series player to complete it, which is a tad unreasonable. For the Diamond Griffey program I'll need to do everything, which will happen as I've been close repeatedly, but it's just going to be a frustrating grind, made more frustrating by how massively affected they are by people quitting and how unpunished quitters are.
Just need to find someone not very good but also man enough to sit through a tough loss, or fluke it and happen to get the hits with Griffey while struggling with everyone else, or get caught in a ridiculous slugfest. All those things have happened before to me, so it's really just a matter of time and patience.
The BR one as well is just luck, unless they change the stupid way it records 8 games to be rolling instead of 8 then reset and then a fresh set of 8.
