PABowhunter-
Great questions......I jumped a little too soon on the previous list of bows. Although the BPF is directly connected to efficiency, it's noit everything. The SQ2 has a higher BPF and therfore more efficient it wouldn't necessarily create more power. It creates about the same amount of power with less work! Confused? What is really more important in the original question is actually more simple than I made it. Any bow that has better IBO or AMO numbers than the MQ1 will produce more energy. It's that simple.

Now to answer you questions. The limbs, cables, cams etc....all matter to the bows efficiency! It doesn't matter however in how the BPF is calculated because the BPF is calculated by comparing a theoretical calculated speed VS. what the manufacturer published it does. By comparing these numbers the BPF is the result. It is a dimensionless number that in theory takes into account all of the variables for that bow. Now that this number is known it is very easy and VERY accurate to calculate any new speed for changes made to the draw length and arrow weight for any particular setup. (use the BPF backwards) This all only possible if the numbers that the manufacturer post are true and accurate.

Happy Shooting!
