I used to think I knw what that meant and why they are important. After reading the link Buster sent me 

( http://www.network54.com/Forum/79537/message/1305313653/Benjamin+Marauder+P-Rod-+Performance+Results+With+Various+Transfer+Port+Diameters ), now I'm not so sure.

 

 

Shot count and power generated are controlled by these two, I think. And I'm going to guess that some quilatiy time with my Chrony is in my future?

 

And should I put my P-rod HDD in and change the TP before starting down the adjusting path?
