[AFMUG] Dumb UBNT speed test question

[Jay Weekley]

When performing speed tests on UBNT radios such as a Powerbeam M2 I've 
been told that the real world throughput is about 55% less. For example, 
a speed test of 10 Mbit/s will actually be 5.5 on Speedtest.net.  Is 
this still correct on more recent firmware versions?
