Im not sure if anyone has made others aware of this scenario ! I fuss an awful lot about my controller boxes etc but when it comes to my elements I just guess distances for wiring etc . And usually a bit longer as such (better than being too short ! But have found over the years and once again this year having too many power cables over data and e131 cables creates flickering pixels once again easily solved ! Just seperated the culprits and wallah! But have always thought is very similar to audio situation !
