If you filled your S10 to 200 bar max each time you would get 15 fills, and regardless of what BSA say the reg does not like input pressures above this. After that you will get many more fills but to a lower pressure.
The same calculator says 31 fills if you limit your fill pressure to 180 bar. That is when your 12L bottle will be down to 180 bar and then probably another 20 fills to 160 bar.
The real world difference is you will do many much smaller top ups rather than always doing full to empty fills so the actual numbers you want to know are how many pellets can you fire before your bottle needs refilling, I would estimate about 2000-2500.
HFT, for people with only 2 buttucks!
