Darn, it looks like I missed out on a great technical discussion....again...<img src=icon_smile_sad.gif border=0 align=middle>

I guess that is what I get for having to go to a seminar yesterday...<img src=icon_smile_wink.gif border=0 align=middle>

Both Black Frog and Jeff have this pretty much nailed down but in order to make it simpler for less technically oriented folks...

...When all else is equal, the draw force curve has no effect on the Kinetic Energy level delivered between two bows producing the same amount of speed with the same weight arrow.

To put into even more practical terms.....a 60 lb Bowtech Patriot spitting out a 400 grain arrow at 290 fps isn't generating anymore kinetic energy than a 70 lb Mathews Legacy shooting a 400 grain arrow at 290 fps though the Bowtech might have a more plateaued draw force curve.

I think that is what you are asking.
