definitely there can be dirt of the downhill leg as well, that's what I meant above by:
due to various factors, not excluding how clean and complete the OLR is.
However... what I'm saying is that a push off the downhill ski is a complete absence of release. That is not dirt, that is "absence". if you read what was claimed earlier, they were making the claim of "pushing" off the downhill leg to actually move the CoM up the hill over the uphill ski. there is no release in that at all...that is complete block and absence of release. And that is also not merely riding on the extended leg longer, that is an outright "push".
We can of course vary the DIRT of our release and in combination with extension DIRT on the other leg...will have a great many different outcomes including retraction transitions on highly flexed legs, all the way up to long leg through neutral up and over that feels more like vaulting.
Pushing on the uphill ski is not a release. Releasing is releasing. It is releasing the CoM from the centripetal forces coming from the old outside ski. The ILE school of thought is that a tiny nudge out of balance upwards on the old inside ski will cause the CoM to vault up and over without actually ever doing anything to relax or release the downhill leg. Ok.. That would be the far extreme case of DIRT. That would also be the slow way down the mountain and generally speaking any and all ILE types of scenarios would be enhanced by at least a small amount of OLR to get the leg out of the way.
The fastest route down the mountain is to let your CoM careen down the the mountain like a freight train without changing its direction. Every time you change the direction of the CoM you slow down. You want the CoM to take the most direct line possible, and that includes vertically, if your goal is to win races.
Also think about what happens when you "vault". You go airborne. Vaulting lifts you off the snow. releasing your downhill leg, at least a little bit, allows the CoM to crossover and keep you glued to the snow. It also can help facilitate a weight transfer to the uphill leg and ski
