What means when CCQ is over 100%?
P2P link, SXT, 5.20
It means that RB it’s a “foreseer” 
, knows what will send before it willl send.
CCQ max is 100%
All other links are up to 100%.
So unless I’ve point my link over a wormhole I don’t know what is going on (I will play around to raise those 69%).
I’ve reduced power (didn’t help, it was reduced already) but when I enabled Nstream
/interface wireless nstreme> print
0 name=“wlan1” enable-nstreme=yes enable-polling=yes disable-csma=no
framer-policy=none framer-limit=3200
It’s 100%/100%
Mistery still didn’t solved 
I would say it is a bug, but I like what MikroTik did there, so better they don’t fix it 
using nstreme protocol sometimes you could get ccq values over 100%. You don’t need to worry about that as the link works at the max possible rate and doesn’t have lot of retransmissions.
I had it before I’ve enable Nstreme.. After enabling is OK.
Using 802.11a/n on 6.18 and I have also CCQ above 100%. No nstreme ever used.
Looks like the calculation formula has some problems, probably not reading inputs for calculation at the same time.
Even it is not important, should be corrected (but not by artificially limited value to 100!!).
I get around 107% CCQ on a 802.11 5GHz connection on Audience.
maybe is a way to reflect frame aggregation gains when you transmit one but acknowledge multiple frames
