Recommended RSSI for setting up mesh access points

We are doing some investigation into setting up some wireless mesh access points, and wanted to know what the recommended 5ghz RSSI was between 2 APs connected via mesh.

I would think that the recommended RSSI would be dependent upon the throughput that you want to achieve.  Can someone else jump in and and comment on whether I am on the right track?

Others here can tell you what values they've had success or failure with, especially with multiple concurrent clients, but as an initial starting point I suggest around -60 or so. In order to get the physical coverage I wanted in a troublesome area at my house I settled for -72 for my AP230 mesh point, and while I now the coverage I need that one area is noticeably slower than elsewhere...

By default (based on the actual Hive settings), the Aerohive system will only try to mesh with neighboring APs if it is > -80dBm and can be adjusted to work up to -90 dBm and as strong as a -55 dBm setting.  That being said, what Dawn and Mike said really as well as environmental factors will dictate your decision here.  

If overall throughput is of minor concern, the link will work at very low data rates.  I've got a couple of mesh networks covering practice fields at a college campus where data usage is minimum and the links are in the -70s to -80s and things work when needed.  If it was a highly used area, a better association between the APs would have been desired and we'd have ended up using directional antennas or potentially using more mesh APs to improve the backhaul link quality.
