PCP air usage efficiency calculator - online

[lloyd-ss]

For those of you who are hard core into the air usage efficiency of PCPs here is a calculator that I worked up for the web and my wife was nice enough to do the web programming for.  

calc.sikes.us

Just click on the link.  There is no www in front of it.

I started this on the Big Bore gate a while back, but I know many of you who don't frequent that gate might be interested.  Please don't bust my chops about putting up similar stuff in two places.  LOL  
 
Right now the only calculator there is for PCP Air Usage Efficiency, but I'll be putting some others up shortly.  Bob (rsterne) is the serious statistician on that stuff and taught me a lot about it.
The efficiency calculator basically tells you how much pellet energy you are getting from the air that the gun uses.  There are two ways of measuring it:

FPE per cubic inch of air (bigger number is more efficient)
and
bar-cc per FPE   (smaller number is more efficient)

They are pretty much the same thing, but one is the inverse of the other with the cc-cuin conversion thrown in.

This calculator can be a tool for working with PCPs.
Bob gave me some  ranges that you might expect to see from different types of PCPs:

Loud, overpowered, inefficient.... 0.6 to 0.8 FPE/CI (20-27 Bar-cc/FPE) - (big power at a high air cost, just a few shots per fill)
Powerful, useable efficiency.... 0.8 to 1.1 FPE/CI (15-20 Barcc/FPE) - eg. Modded Disco, MRod, Hatsan
Moderate power, good efficiency.... 1.1 to 1.4 FPE/CI (12-15 Barcc/FPE) - eg. Stock Disco, MRod, Hatsan AT44
Low power, high shot count, excellent efficiency.... 1.4 to 2.0 FPE.CI (8-12 Barcc/FPE)

Enjoy it folks, and let me know if you have questions or suggestions.

P.S.  Thanks to rsterne and mellowroadman for doing the beta testing this evening.

thanks Lloyd, this is awesome

Guys,
Glad it's working for you and I hope it's helpful.  Let me know if you have any suggestions.  I've got a few other calculators in mind that I haven't seen online anywhere yet.

It's a small point lloyd, but if you could place your efficiency number's from above somewhere on the page it would be a helpful reminder to first time user's(or those of us with a few dead brain cell's).

Jay,
Good suggestion.  I had actually thought about that and then was just excited to have the calculator working..... then forgot about the eff range numbers altogether. 
I'll talk to my web programmer (wife).
