Need to pick your mind about binding mechanics: Does "function properly" mean just the usual lateral release at the toe using a piston?
For example, having a full lateral - or even MRR style partial lateral - release at the heel might well change the settings and forward pressure for a lateral release at the toe. The old MRR's had quite a bit of lateral give because of the design, but I assume if we can measure release on a modern FKS, we can handle a MRR. (Although I've never noticed any shop interest in measuring the impact of vertical + lateral at a Tyrolia FD heel, since the lateral doesn't kick in at 180 degrees.) But I'd guess techs now have to think about full lateral with KB's. Does it require one check in front and one in back? And we have plenty of vertical release toes mated with the usual vertical release heels, so I guess that's also measurable. (Although shop guys tend not to measure heel release using instruments, I've noticed.)
But delta might differ between the design parameters of the toe and heel pieces, as might AFD's. And AT platforms would also have different weights at the heel, which changes loads acting on the toe. I'm assuming an empirical check would cover all that. Wrong? Right? None of the above?
