It's pretty simple math. Take your clip length, the length to your flasher and your leader length and assume that it all could kick up at some degree of an angle toward your second set. Personally I maintain 30 ft between gear. Another thing that can happen from time to time is if your clip is sliding up your downrigger cable on your bottom rod then it can decrease your spread as you keep tightening your rod back down. Plus never ever stop the boat. When turning into the wind or current make sure you increase your speed so your lines stay well back.
Good luck!
