Just my 0.02 cents here.
As said above, riders usually go too fast from Ben's step 1 to step 6. One just must practice every step so much that it comes automatically correctly. And i think at beginning it is good to over rote upper body. Then later it can be dropped to proper level, for me it helps to get better feel to turn and rhythm.
And another point is not to move steeper slope too early.
Unfortunately it is PIA to make same silly practice in same not-so-deep slope but that is easiest way to learn due then you can concentrate what you do and not control speed.
Push-pull is fun way of riding and it is no way related to any style, just another tool in box.
But we all want to learn everything in quick way. And euros are fun to do, once you feel it.
