As you add more teams it increases the data hash exponentially and thus takes much longer. 50 teams isn't too bad, 700 is a little out rageous

That is about what I figured. It sounds like it is very feasable to do near real time at an individual event but the overall across the board rankings would have to be done as post event analysis. Which, of course, would work fine since at an individual regional I don't think teams really care how well another team at another regional is power ranked in real time anyway. So basically a system like this could possibly be used instead of the current FIRST W-L-T/RP system. The question now is is it really appropriate?

Hmm, something seems odd then about the rankings. For example in the overall rankings the first group with the same power rankings are ranks 10-12 (1305, 1024, 1466) with 88 points. Not really in any order that I can determine. Is there maybe a decimal something behind the 88 that we can't see? Not that it matters that much I am just trying to see how this might work at a competition.

I was thinking of this mostly from an overall scouting prospective before Atlanta Nationals so I would think it would only be run on the static data from previous regionals. I'm not sure which would be a better indicator now that you mention it. Probably the relative power I guess but maybe other folks have a better idea. I was just trying to think of a way to get a feel for if more of the top ranked teams went to multiple regionals, how much better they got from one to the next, etc.

That might have some interesting metrics

It would also be interesting to look at the Atlanta Divisions statistically and see if there really is a harder division. Statistically I bet they are all pretty close.
