Yes, Weems, I do see something going on technically. But first a couple gold stars awarded. One to tdk6 for keying in on the problem, and one to ssh for recognizing the recreational skiing application. Well done.
When Bode came on the tour he displayed occasionally brilliant section times, and very infrequent solid runs, scattered within hoards of DNF's. Bode knew how to go fast, through straight lines and the use of the skis tails, but he lacked the intelligent discipline re-center his fore/aft position for the start of each new turn. He would live in the back seat, and eventually it would catch up with him, resulting in either major time burning mistakes, or termination of the run.
Finally, a few years ago, someone or something got through to him, and he started moving strongly to the front of his ski at the beginning of his turns. He still skied an aggressive line, but his forward position at the top of the turn allowed him to go straight, yet remain in solid balance and control. And he still used the tail at the bottom of the turn, but just not so drastically that he couldn't recover to a fore position for the start of the next turn.
That single fore/aft balance platform change was all it took for Bode to emerge as a dominant slalom force. His finishes became very consistent, and he produced strings of wins with some mind blowing victory margins.
The next season he decided to place a major focus on speed events also. With that broadened focus his new founded slalom approach seemed to begin to revert back to his old back seat habits, and again the DNF's started to return.
Like JohnH pointed out, the speed event focus has cut into his technical event training time, and he never has been able to recapture that consistently well balanced top of the turn form he possessed for that one shining season. In fact, as time goes on, and the frustration level grows, he seems to be gravitating to more and more back seat tactics in a desperate attempt to return to the podium. It's a dead end approach.
Contrast his skiing to that of Rocca, who's constantly in perfect fore/aft balance. The guy uses almost no tail tactics, yet he dominates the slalom event. This is the lesson for the recreation skier to learn; the importance of maintaining good fore/aft balance throughout the turn, and then moving forward so that the CM leads the feet into the new turn, creating a solid new edge engagement.
Bode still could return to being competitive in slalom, but he's going to have to abandon the hell bent for glory mentality, and get back over the top of his skis.
And Fox, I strongly agree with you. That mouth of his ain't doing him any good either, but that's beyond the scope of this technically based discussion.
Finally, Alaska Mike, you and I are coaches. We don't give breaks, compassion passes, or rationalize. We watch, analysis, and tell it like it is. If a racer doesn't want to listen, or would rather direct his focus else where, that's his/her call. And if we can help others learn by pointing out Bode's current technical flaws, regardless of their external origin,,, well then,,, we should.
