Parts 10 & 11 deal with barrel length.

What he calls the "power valve" is a base 2240 valve.  The other is a 2300 target pistol valve which is a lower power/higher shot valve.

Re 13xx the numbers will vary but the principle is the same.  Longer barrel=more power/FPS.

Accuracy is determined by the quality of the barrel, not the length.
