Let me put it a different way.
You can take any compound bow
design and increasethe poundage (of course you may need stronger limbs, risers, string, etc) to reach KE energy levels at mentioned.So the KE alone mentioned doesn't impress me.
The most efficient bow will reach these KE levels with more energy of the bow going to the arrow instead of being dispensed otherwise and will take less work from the archer. That does impress me.
Im not getting into commenting onsuperior claims etc. I also won't get into claiming what people look for in a bow is right/wrong either.
When we're talking about the modern companies producing compound bows......is this that big of a concern?
I would think effeciency would be a concern for the little as well as big company when designing a modern compound bow.
