SCW, we never post another URL on Ricks site, Just kidding I would venture to say that from what I have read in different publications and loading manuals that no, you can not compare the two as far as a correlation due to the two different methods used to measure the pressure, they are doing two different things to reach the readings given but can not be safely assumed to be the same. Due to how they both measure the pressure, one measures basically the peak pressure and the other will give you pressure curve and duration I believe. But hopefully the good Doctor will add some more wisdom.

Partsman,
<br>The argument that this fellow Denton makes is that ultimately, all measurements are of the peak pressure, and there is now way to determine otherwise. For example, if you measure the amount of copper crushed, how do you know that it was crushed during peak rather than sustained pressure? Ultimately, the measurements are of the same thing. Pressure in the chamber.
<br>His idea and solution looks good to me, but I can only look at his numbers and nod, as I have no way of proving or disproving them.
