I'm no expert but to me I almost think of them as being the same. The manufacturer of the bow basically tells you where your sweet spot of your cams are by giving you the axle to axle distance and brace height dimensions. What I do is make sure the ata distance is correct by twisting cables and then remove from press and see if cams roll over close to eachother if not I twist cables to get close as i can guess. I read an article on creep tuning which the process is basically you take a peice of tape horizontally on your target. Shoot at the tape when you pull as hard as you can against the back wall and then do thesame thing only on the next shot let the cams creep to the front wall and if the shots hit in the same spot than your cams are timed. If not you have to twist or untwist cable a turn or two to correct. Once you have successfuly done this process it is amaising how that errant 5" high shot goes away. Search for creep tuning and it should help answer your questions. They're more in depth procedures on other forum pages. I dont know if that is the answer you are looking for but might be a place to strart.
