What I mean is how you look at the relationship cuff pressure and force on the ski. Studies have shown that cuff pressure does absolutely nothing for pressuring/bending the ski. The ski bends because of force. Centripetal force, gravity, your weight etc... The position of your CoM decides where that ski is going to bend, because (to simplify, not entirely accurate, cause not all those forces move in the same direction) that is where all those forces will be doing their work. It so happens to be that if you want to bend the ski a lot, you want to position your CoM in a way where it is likely that at some point in the turn you are going to feel shin pressure. That shin pressure however is a result of the position of your CoM and not a goal in itself. The shin pressure in itself does nothing. I could mount your binding position all the way to the back of your ski and you can ski with all the shin pressure you want and you'll never be able to ski the same radius as someone with a neutral position, with little cuff pressure and the binding mounted in the 'middle' of the ski if both skiers are skiing on the same ski. What a ski boot does do is that it absorbs loads that are being exerted on the skier. So a ski boot in that sense makes life easier for us, and that is what gives the power feeling. But in theory you should be able to ski exactly the same with unbuckled boots.
Hence shin pressure is never the goal. There are 100 ways to have shin pressure and I could contort my body in all kinds of ways where I would have shin pressure with a CoM that is extremely far back. I could for example bend my ankles a lot to the point I would have shin pressure, but then bend my knees even more to a point where my whole body from the knees up will be in the backseat. Even though I would have shin pressure, that would be very counter productive. On the other hand I could also have shin pressure by leaning into the cuff and skiing like Michael Jackson. Same deal, I would have shin pressure, but it would be counterproductive. Being centered is key, and once you're balanced and centered everything else doesn't matter. Sometimes being centered means there will be shin pressure, sometimes being centered means there won't be any shin pressure. So the important nuance is about the relationship CoM and shin pressure. I want my CoM in a good position and then I'll probably end up with some shin pressure some of the time instead of I want shin pressure and we'll see where my CoM ends up.
Maybe @Jamt you still have some of those boot/interface studies at hand? I have a new computer and lost a lot of my files.
I would love to see that study, cause from what I know that is not necessarily true. The only study I know of that sort of looks at bending the boots is the Birdcage-experiment (1988?). And even that didn't really look at bending the boot, but at pressuring the boot. The WC skier was skiing very neutral. All other studies I know of that study boot/ski interface and all things related look at loads (as in force) and not at the degrees a boot is bent.
I'm aware of certain groups of skiers that advocate a centered position, but for competition mogul skiing the goal is to pressure the shins, and it does have real physical benefits, because it increases pressure on the tip of the ski. Olympic mogul skiers will tell you to pressure the shins for short radius turns. You can turn sharper by pressuring the tip. Also, the tip digging in can provide speed control on the backside of the bump. One way to visualize it is to imagine that the ski is tipped with a steering angle at the beginning of the turn. If you can apply pressure to the tip it will bite and bend. Once bent, the ski will arc according to that bent radius. I believe your analysis is entirely based on sidecut, and that's an ideal approximation to a good carved turn, but ultimately in real skiing there are many factors that control a turn. If you just want to do perfect RR track turns with a carver ski on the groomed, then centered is best, but if you want to try to get lots of different types of performance out of the ski based on different circumstances, then you may want to apply shin pressure at times. If you want to do quick short radius turns with speed control on a mogul ski, then you definitely want continuous shin pressure.
