The "Delay on" and "Delay off" have always seemed backwards or mislabeled to me. I'm running 2630 display with 1790 planter with black wedge box (gen II XP, I think) with ECM's, so I don't have the handy performance tuning screen. I have to calculate it out. I get the numbers correct, but I always go the wrong way. Using the example in this video 11" overlap @ 6MPH going from end-rows into the field needs 0.1 second (11in/((6MPH * 5280 ft/mi*12in/ft)/3600 sec/hr)=0.1042 seconds). Since it is an overlap, my reasoning tells me to add more "delay" (0.5+0.1) before the row turns on to eliminate the overlap, but that is the wrong way and results in double the overlap. It would make more sense if they called it "look ahead time" because to reduce overlap by 0.1 seconds, I would need to reduce the "look ahead" by that amount (0.5-0.1=0.4 sec). I hope I'm not alone in this, I get it wrong almost every year.
