Never go by what the cam or module says. Your true AMO draw length and what the bow says are often two different things. Many bows are actually longer than what they state, mathews used to be very bad about this. It helps them fudge the IBO numbers. IBO is not really a standard, it is just a 30 inch (rated) bow at 70 lbs shooting a 350 grn arrow. So they can use a bow with 70 lbs limbs on it and a 30 inch cam or modules. They don't actually measure it. It might be drawing 72 pounds and up to 31 inches when they test it.

AMO is a standard and everything must be measured and verified. It is a much more accurate way to rate bows. However the numbers are not very impressive so companies quit using it.

Also keep in mind your draw length can change depending on your set up, form and the design of the bow. I have three different bows and they all have a different draw length depending on how they are set up and the release I decide use. My draw length is normally between 25 and 26 though. My darton at 26 inches was a bit long. On my mighty might I am a hair over 26 inches.

You really need to fit the bow to you, then measure the draw length for future referance. This is also why you can't buy a bow without shooting it. It is very important that a bow be set up to fit YOU. You can't just order a bow off the net or buy one off the rack because it says it's 28 inches and you shoot 28 inches. Things are not always what the apear to be. Especially with the newer solid wall cams. Used to be with round wheels and eccentrics with a large valley it wasn't that important since your form and anchor points determined your final draw. Now it has to do with the stops on the cam/s and they need to be set up fairly accurately. The more our technology increases the more important the set up becomes.
