Is it 0.7 or 0.5 of resting?
And is it age dependent and falling as we get older and is that why I now need a much warmer sleeping bag?
I’ve seen it stated as an extra 5 degrees of comfort warmth needed for every decade after 30YO and also seen it as after 50YO
After 30 seems to gel with my current needs, my new -8C bag was cool to cold at +10C in the back yard, on a cot with a good mattress but no tent or fly
