Found this while doing a lot of web searching, very useful IMO.
According to info I have found Benjamin Discovery has a 135 cc tank so using this calculator a Guppy tank ( 17 cu. ft. ) starting at 4500 PSI and toppping of Disco from 1.2K to 1.8K should be around 51 fills down to 1.8K

Chart here list Disco as being 126 cc. , many others list also

Nice
thanks for the links
I looked at that calculator and thought , so that is why so many on the GTA site get so confused trying to use it. I find the one I provided link too much easier to use but then ,different strokes for different folks.
