Condensation in the Cuben Grace solo tarp

Regarding my UL camp here...

I added this to a Facebook post, but it seemed prudent to add here and link to my UL Dartmoor camp with the MLD Grace solo tarp.
Regarding a lot of condensation under the tarp...

I guess the high humidity didn't help, it was very warm (we have had over a month of heatwave) and then rain and mist appeared, so I guess inevitable?
That's my first pitch of the MLD Grace in probably over a year and wanted to pitch it low as rain forecast. Maybe could have pitched rear a bit higher but didn't want rain being blown in. My poles are 1.2m long tied cord at top but probably could have made front nearer top, again didn't want rain blown in front. That kind of tarp is a big learning curve.

I'm sure a Trailstar or any shelter would have had as much condensation? Or maybe less due to being more closed and mist not getting in. Absolutely no idea.
All good fun in nice weather. I'd not be so keen in bad weather. But have seen these used in freezing mountains! Ruddy eck lol!!!

I'll be interested by the thoughts of others (and Chris Townsend) if they get a chance to watch it. I also need to research / pitch and play with this and rectangular Monk side by side to compare. As whilst they similar they different. I did notice this "dipped" in centre I think due to cut / cantanary cut here, it was very taut. It didn't move in the breeze! But breeze died down as the evening progressed.
I'll be interested in the thoughts of others.

From Zelph -
Trying to get a second boil after the stoves has been cooled and the lid put on is going to be hard to do. That second 1/2 ounce is primarily on the bottom layer of the stove. Vapors are being covered with the absorbing material. In order to get the vapors up to the top again I suggest the jet type. One of those would get the stove hot and would then ignite again.

One thing to try is hold the stove upside down and use a regular lighter so all the heat is concentrated on the center of the stove for 10 seconds or so.

Normal useage is to fill the stove with 1 ounce and heat your water. Blow out the stove and the remaining fuel is captured with the lid. When the stove is used again, 1/2 ounce is poured into it and then used. That same procedure can be used over and over again. Practicing at home under calm conditions is recommended.

and here is a pointer to the original thread over at Whiteblaze.net where I first showed the video in cold windy weather:
