I think MtnFreak's argument is that even though you can boil water faster with the PR, it is using more fuel regardless, so you get less use per canister (did I get that right?). So, I think another test that would be helpful is how many litre's of water can you boil per canister on each stove using the larger JB pot? If MtnFreak's calculations hold up, it may take longer with the JB, but you will get more use per canister. I don't know the answer and hopefully we can coerce you into performing another test RideT61. Good thread
