I'm wondering how are they calculate ? I've got link 9 km and I'm getting very strong signal -49 to -50 dB. But those variables are standing low and unpredictable about 20 to 30 percents. The links are connecting with 36 Mbps, and 20 % are about 8-9 Mbps, which is the real amont of data transfered throw the link (watched by torch).
Where could be the problem?

I'm starting preparations for upgrade from 2.8.x to 2.9.x, but I don't think I'll resolve the problem.
