I could add a setting to select the amount of beacons per machine you want. The issue is, it's not the same for all entities but maybe I could just make it for 3x3 entities, 5x5, and miners/pumpjacks. That'd be feasible.
For now what you can do is unpack the mod and edit beaconed-functions.lua. There are values like global_assembling_machine_beacon_count = 12, and global_assembling_machine_average_beacon_count = 7 . You can change these to whatever you want and the mod should re-calculate everything properly.
I'll add the setting, but I'm not sure how quickly.
