Edgun – filling the reservoir

Hello,
I have a question about the number of refills a scuba tank can provide.

I’m buying a Edgun Matador R3M Small, so the reservoir has 236cm3. On average a 3L Scuba Tank of 232 Bar can provide on average how many fills?
I just want a number to see if it’s worth buying such a small tank, but thats the only one I can get now, the other offers are only 10L+ tanks
