I'm afraid I don't agree. As a previous poster said, power is power, focus is focus, clarity is clarity--and a knowledgeable martial artist at black belt or above should be able to recognize that in any of the external styles. Nearly all the time, anyway.
A few years back, I went to a well-known torunament, and watched the black belt forms--saw a woman in an Okinawan style who SHOULD have won, for all the reaons I just mentioned. Instead she didn't even place--flashier forms from guys prevailed, including one (sorry to say) by a very advanced kenpo guy that was just plain awful.
The problem isn't knowledge. The problem isn't even politics, in a sense, because THAT would balance out. The problem is that we've let some fundamental dishonesties creep into tournaments and forms and judging--for example, the often-repeated, "I had to change the form so it would look flashier for the judges."
As things stand, I'd bet we'd all be pretty horrified by the results if we were to somehow get a fully-objective look at scoring and judging. My offhand guess is that things are worse than we think.
