How many APs from one location are you configuring......if its 3 or less, I call BS on needing capsman.
I ran caps man on my hAP AC2 router with it's wireless disabled. Then the only cap being the Audience I have. Seeing all 3 radios in real time on my router was nice.
And I am guilty of using caps-man to manage 2 or 3 Mikrotik WAPs, in many sites.
However... I found that I still had problems with throughput and devices connected to 2.4.
Since moving that Audience to a 3 radio WAP running the WAVE 2 drivers... I have the best wifi performance I have seen out of a Mikrotik WAP serving clients. But that kills caps-man and several other Mikrotik radios features.
But I get downloads 50~60% faster in the same spot with the same amount of clients spread across all 3 radios.
