Overnight I got cold enough to wrap the tarp underneath the hammock as a wind block...I was immediately warm enough to sleep. If I had to estimate, I'd say I felt 10-15F warmer just by using the sil as a windblock...like I said, it was a big enough difference that I could actually sleep. This matches the earlier comment about wind making the underquilt feel colder for a moment as well...maybe the wind is cutting thru the DWR rather than just seeping in the edges from a poor fit?
Anyway, your logic sounds reasonable but I think wind is another variable to consider re: the difference between sil and 1.1 oz DWR.
