Anyway to get a ELI5 for SM grouping?

Hey there, I'm a fairly low level tech support agent for a WISP, but I'm looking to learn more information about networking. I've got certs that contain just the surface of Cambium EQ, but as I've been getting further training, and a recent promotion, information on Cambium grouping has not been explained to me well. It's like they explain it as a highly specific situation by situatuin basis and I'm having a hard time understanding it. I'm not even sure if this is a good place to post this but I am genuinely curious, how do I tell if a SM is grouping correctly in the spacial utlisiation page? Does the "instantaneous %" tell me something? From what I understand as well as "sounding statistics" has an impact as well, we want them all to be tracking and not untrusted. Basically what I'm looking for is a laymans, dumbed down easy to explain grouping if that even IS possible. Thank you guys, and please direct me to the correct forum if I need to post somewhere else.
