Palm Springs Air Isn't Neutral
Desert heat and elevation both change how far a ball carries for a given swing, and a number recorded on a 108°F July afternoon will not match the same swing on a cool December morning — let alone a fairway somewhere else entirely. We log temperature, elevation, and humidity at the start of every session so the reading is anchored to something real.
That's why every session ends with a two-column sheet: what the club did in the room that day, and what the same club is likely to do in cooler, denser air. Players tell us the second column is the part they end up using most.
What Gets Logged Every Swing
Ball speed, launch angle, spin rate, spin axis, and carry & total distance, each swing — plus room temperature, elevation, and humidity recorded once at the top of the session and printed on the sheet alongside the numbers.

Every session runs on this same setup, logged and corrected the same way.
