Not everyone keeps up with their dance education, and some get stuck in old technique or opinion. Our body mechanics are continually being refined on the competition floor, just as our auto designs come from the racetrack. Not everyone is in touch with what is currently successful. I think many of us have probably been through the scenario you describe. Sometimes such a coach has other things to offer (choreography, for example) - but I think we instinctively know what the problem is, and what to do about it (and particularly regarding what a coach costs us), when we ask the question - we just don't like to do it. In my area, I've concluded that it's better to have coaches who are active Pro competitors. No matter how they may stack up against the awesome other pro competition, they are in touch, and have credibility of technique which they are proving frequently in the crucible of the comp floor, versus hiding out in the studio. Instructors have to be masters of self-promotion to be in business, like realtors or lawyers have to be, and like lawyers, there is no sign on the courthouse that says "Bill 2, Harriette 6." But I feel that if a coach is spending time on the comp floor, just like a lawyer who is actually practicing law by litigating versus talking and writing, one may have superior goods - and even if they are not the placewinners, they will know where their own strengths & weaknesses are in terms of current advancement, and train you accordingly.
