How do you determine the max draw length for a given bow?

It's all in the headline

Draw the bow until it explodes.

Max draw length is 1" less than that.

When the string angle reaches 90 degrees or begins to stack mean you have used up all your limbs bend. Now to get the best at your draw the bow should be just starting to stack meaning you are getting everything they got to offer.

Write down draw weights at each inch of draw.  When the change changes, ie;  goes from 3# per inch to 5# per inch , you are there with the last 3# change.

Also look at  the string angle at full draw, if it is past square with the limb(which is kinda hard on bows with curvy limbs) it is prob there.

The change in weight way is prob better...
