Justin,
As this is something your taking your own time to do, I think most, if not all of us appreciate it greatly. This may be the only place to find this kind of compiled data on the makes/models etc. Be a couple months or a year+ to finish crunching your numbers, this thread will be up for a long time so a lot of people will probably get to use this information.
Personally I am looking forward to seeing were in the numbers my own ti sits. (97, active, boston green
