I'm just starting to make some good use of your stats reporting for a new group of projects. Sure, I'd love to have the wealth of information that choice #3 would give me, but realistically, I won't be able to make use of it all right away, so I'd rather have less info sooner. On that basis, I'd be happy with #1 or #2, whichever one takes you less time to compile and release.
BTW... thanks for doing this.
