[QUOTE="benchracer, post: 960122, member: 22069"] I found a barometric pressure vs altitude table to help me do some rough calculations for the tested elevations: [url=http://www.sablesys.com/baro-altitude.html]Sable Systems[/url] Plugging those numbers into the calculator you provided indicated that, with my chosen load, the 69 SMK's would stay above Sg= 1.2 down to about freezing @ 1860 ft ASL and down to about 45* @ 1000 ft ASL. I am sure that having the ability to measure actual temp and barometric pressure would give me more accurate and useful information. Still, it's nice to have at least a ballpark idea of what to expect. [/QUOTE]
