My understanding is that modern flight computers (which seem to have 10X more features than anyone could possibly use) don't make adjustment to STF calculations for the wind. From my reading of recent "authoritative" sources (Brigliodori, Kawa) it is optimal to increase speed into the wind and decrease speed downwind, relative to non-adjusted McCready. Also of critical importance to me would be a final glide optimizer. Currently when making a final glide I "move the dial" up and down in McCready speeds as I get close to final glide. Often changing the McCready value up into the wind and down with the wind leads to lower required altitude.

Am I missing anything?
