The top 100 list in Boston is somewhat poorly named.. as of today, there are only 71 ladies there...  
seems that there are a significant number that could be added?  

Just an observation.

gets you bumped from the list .... and a few other criteria (maybe) might also be on play. I know several gals that asked me not to do a review because they didn't care. One wanted to start flying more UTR.

I recently recall one of the Top 4 fell off due to no reviews in the 3 months thing.

"the recent unpleasantness" (as they say in the South) dropped a few more off the rolls.  Lots of new providers haven't hit 20 reviews yet.

Looks like they're reaching pretty far down when you get to the 70's.

There have never been more than 70 or so (at least since I discovered that the list existed, which was some # of years after I joined TER).  I always assumed that the average of the two scores had to be above some level and that's why it stopped at 70.

I think you have to have at least 20 reviews, some minimum number of which are within some "recent" time, and also there are some non-visible criteria buried in there somewhere.  There are people who would certainly qualify who have Boston as their primary city but don't appear on the list.  When one dropped off I asked about it and was told that they "weren't eligible" (they had >20 reviews, high scores, some recent, so I guess there are other factors, or maybe you can request to not be on the list if you just aren't into it).

I guess one could always make it a goal to see #1 through #71 ... but then you'd miss a lot of great folks with 9 or 19 reviews!

Some of the best ladies I know are not on this list either because a) Don't have min 20 reviews or b) don't have one for 90 days.  Many of the best, most established ladies don't need or want new reviews.  Use Advaced Searches to find the gems in both these omitted categories.

I'm working on getting more good reviews so my name could go up that chart too.
