Can I convert acalculated energy figure into approximate draw weight?

Badger:
 There is no difference between draw weight and measured draw weight they are one and the same.  The levers may produce a bow with a higher force draw curve meaning they store more energy than is typical for a specific bow weight. The bows stored energy is simply another measurement. Typically, a bow will store a bit over 90% of its peak draw weight in foot-pounds of energy, A very extreme bow may store 110% but that is very extreme.

The performance of the bow is terrible, far below what I had expected and I would like to know how hard the limbs are working.  I think the centre is too weak, possibly the tips are too heavy, and the string is too thick.  I even wondered if the arrow was too heavy - its not, I went to the post office and weighed it properly........I will lighten the tips and make a new string and increase brace height a little.  For fun, I sinewed it to see what difference that might make but I didn't find a way of stopping the string sliding down the limb before a really hot day gave perfect conditions for applying sinew.  When everything has dried, I'll put on a leather wrap and draw the bow at the end of the working limbs and at the levers and see what the difference is.

bradsmith2010:
what is the perfomance
length of bow
arrow weight
draw length
any pictures,,

superdav95:
Agreed.  Would be nice to see a few pics of the bow too. 

Badger:
I get more confused each time you answer a question. If it is a regular bow why can't you just put a string on it and check the draw weight? Levers and working limbs don't need to be accounted for when measuring draw weight.
