Weather Variables
GROUP 1 Atmospheric Density ⚠ Pick 1
Density Altitude = temp + pressure + humidity in one number. Use it alone — adding the others double-counts.
GROUP 2 Combustion Moisture ⚠ Pick 1
Water Grains = actual water per lb of air, most direct combustion metric. Others encode the same moisture differently.
GROUP 3 Wind — Fully Independent
Zero overlap with Groups 1 & 2. Always safe to combine.
Mixing variables from the same group double-counts the effect — accuracy drops when you do this.
