[QUOTE="Pdvdh, post: 440410, member: 4191"] I think the correlation of altitude, temperature, and pressure is relative in the present sense, meaning if you set your instrument adjustment to current conditions, the relationship is likely to be present the majority of the time. But I've climbed up into the sheep mountains in 40F weather, and I've been present at the same altitudes when the temperature was 80F. Unless you're going to select and install new turrets based on current weather conditions, the same way you set a planes instruments to the present conditions, I don't see where the rule of thumb would be helpful throughout the duration of a hunt, under changing weather patterns. At least not where I've hunted. Maybe I'm missing something here, but weather is transient - ever changing - and my hunts often last long enough to encounter differing weather patterns and their resultant differing temperatures. Let alone the daily temperature swings from morning to mid-afternoon to evening. Seems much more straightforward to simply obtain the current temperature and station pressure at the time and location of the pending shot, and then determine and apply the appropriate dope based on those current environmental conditions.
