that's REALLY pretty good.
however which size can exactly you used (large or small) can be sometimes confusing, but I'm assuming the large can.
I only say this because small can weighs right around 200gr +/-, but the fuel content is only 100gr, whereas the larger can has 220grams of fuel, but that's not the total weight of can+fuel.
The fact that you used 113gr of fuel, tells me the larger can (since the small can only has 100gr of fuel)
Anyhoo...That's pretty outstanding you only used a little more than half a can, WOW! Terrific management.
I'd caveat this anyway, I don't think folks should assume they can run out and get 10-15 days off 1 large can.
but good job anyway
