Am I correct in saying that maximum compression is created with the least amount of loft (assuming all other impact variable remaining constant)?

If so, why would this be the most desirable?

First, let me say that I do see an issue with Homer Kelley's writings and ball flight. Second, the D Plane does expose a key concept(s) that isn't stated or implied in the Golfing Machine. And that maybe all you are really seeking - now on to your specific questions.

Regarding your first question above - Yes.

Regarding your second question - If so, why would this be the most desirable? The statement of "maximum compression is most desirable" would be in the context of any particular club. Your question to me implies your comparing a two iron to a 9 iron - which obviously isn't what we are doing - unless you want to take it literally - which wouldn't be very smart. Really the goal of maximum compression would just allow you to hit shorter clubs into holes - thereby creating more control based on the shorter club - more loft, etc. As long as you know what you are doing or can consistently repeat it - then that's what's really important to the general golfing public. If you are not shooting for the ideal then there are alot of good golfers that plan on compression leakage - and given any issues in their swing actually use it for a purpose - that is to create less spin on the ball and therefore prevent less curvature on their shots. Essentially - creating or living with compression leakage is one compensation a player can make for other flaws in their swing.
