load based off of elevation and humidity

[double g]

how much should you increase a load from 1400 ft elevation and 30% humidity 95 deg. going to 100 ft elevation 75% humidity and 85 deg to keep the bullet speed and tune on rifle the same. not able to test at the low elevation too far to go to test.

I do most of my shooting in North TEXAS, the DA is usually around 2000 feet, I shoot matches down at Rifles Only in Kingsville, which is basically sea level, the DA there is varies between -2000 to 2500 depending what's going on in the Gulf, I don't adjust nothing, YMMV but not much.
