This is a very nice report. One of the things that jumps out at me, is that there are more options available in the arena than ever. Because of this, it is hard to grasp the information easily.
I agree with the earlier ideas about having a spreadsheet available for download. Ideally (and I have no idea how easy it is to use the software) it would be nice to simply plug the numbers into a web application, so that it would function like a spreadsheet (sort by one value or another, hide columns, etc.). I have done this sort of work before, but it was custom (I would imagine there is web software out there that would make the job much easier). Again, I'm not sure how easy it is; but if your web folks did the work, it would probably pay off as more and more tables are created.
As it is, the tables are very nice and fairly concise. But if the tables can be made bigger, I would suggest the following additional columns:
1) Inside Space (while it nice to have a big vestibule, I don't think it is as important as having bug free space).
2) Inside Space/Weight ratio
3) Entry Method: (top or side)
4) Number of People: (I know this is a bit subjective, but it would still be helpful to have as a summary).
5) Height by the head of a 6' person
6) Height by the head of a 5' person
I'll admit that I am biased towards the last 2. To me, the value of a tent (over a bivy/tarp combination) is that you have a roomy shelter from the bugs. You can lie down and stare up at the ceiling (or sit up on your shoulders and look at your feet). You can also lie down (on your back) and stretch your arms out (upward) which is why the five foot measurement is important. The combination of these two measurements would give you a fairly good numerical comparison of styles. For example (all things being equal) a tent like the Contrail would score well in both numbers (since it is very tall on the end); a tent like "The One" would be better in the 5' test than the 6' test (since the peak of the tent is close to, but not at the end); a tent like the AntiGravityGear would not fair as well. Of course, a very roomy tent (or one that slopes steeply) would do well in all measurements, regardless of style. I'm also a bit claustrophobic, so the room available while lying down is especially important to me.
Thanks again for the report (I love this kind of stuff).
