If your figure is gross, including the canister, it won't be enough.

I just got back from 16 nights in the SW. There is still gas in the single 230g cylinder I took. If it's just for rehydrating dinners and morning porridge, it should be plenty for the OT.

Sorry to get a touch off topic here... But I've been curious about boiling with high heat vs low... and which is more efficient. I'm guessing it's a somewhat complex answer and there would likely be a bit of a bell curve with diminishing returns at some point. Surely if it's too low, you'd be fighting any ambient heat exchange or wind to a larger degree? Is a 'Medium' heat usually the way to go? Any kind of rule of thumb? Am I over thinking this, and asking too many questions?
Sorry again, I don't mean to hijack this thread.

Not to say that it isn't helpful and I know there's a lot of variables at play here. I would love to see a graph of fuel used vs temp under idea conditions to confirm some of it. I guess you'd go through a lot of canisters trying to work that out.

I've always found that blog to be reliable. He does a lot of testing of different stoves in varying conditions. So he likely knows better than anyone. There is some more precise data in other areas of the site from memory.
As you mentioned the challenge with creating meaningful graphs is the variables are significant. Eg wind, temperature, altitude, pot width, lid on or off, heating food vs water... the list goes on.
My general rule of thumb is a medium heat. Lower if I'm simmering, higher if I'm impatient for a coffee. I'm usually quite generous with my fuel allocation so I'm not needing to get the greatest efficiency possible in order to make the fuel last an entire trip.

Although Tony's experiments were specifically to test wind shields and how much the flame running up the side of the billy helps to heat it, it also shows some results from different gas valve settings.
In brief, medium setting is best. Turns out that the flame running up the side of the billy doesn't help much, and is therefore a waste of gas. And as you said, wind is also a major factor - a good wind shield makes a huge difference.

I'd like to go as light as possible as I'm small (5'2") and max out at about 13kgs, but I'm also concerned about the durability of 20D fabric (I dont want to spend $700 on something thats going to rip within 5 uses) so I've been considering trekking pole tents such as the SMD Luna Solo, or Skyscape Scout, that are similar weight as MSR Hubba NX1 and Slingfin Portal, but are higher D fabric. I'd like some opinions on whether these are compatible (will the cup hook method work?) with the platforms and suitable for April weather such as temp and possibility of snow on the track please!
