Hi!
I've been lurking for a few months now, and figured I'd give one of these challenges a go, at least officially.
Number of objects upgraded: 74
Percent of unique upgrades completed: 89%
Total: 74* .89 = 65.86 = 65
Even with the areas I could have improved on had I practiced, I don't think I could have done more than 100 objects tops - I eagerly await January 29.
