You are probably right. It is pointless to argue with people who haven't experienced something. That said, I suspect Graham and I will be arguing about this in 30 years time when we're old and grey.
I would say that in the late 70s and 80s what was taught in Germany was limited - people there just hadn't had long exposure to the LT system. Most came from KK who had not spent years studying. However... what he taught in the early days was mostly what he had learned, and less his own ideas. Over time, he added in more and more of his own ideas, and spent less real time learning. Emin was all about function. So he took the basics and being hugely talented worked them well. He too had some exposure to Leung Ting. Emin, I would argue, got out before things turned too crazy.
That said, I know numerous people who trained under him - many, many years and many, many private lessons. Some of those guys later went on to learn in Hong Kong or from people trained extensively in HK... and they say things are very, very different.
KK has huge talent. No doubt about it. If he wasn't, he would never have built up the EWTO the way he had. PB has no love of KK, but I think you'd find even he would admit that KK was talent: fast, powerful, good control. Like I said, in the early days the EWTO was kinda hardcore - they trained tough. Then things changed - in a BIG way.
Being kind, I would say it is different today. Being honest, I would say the EWTO went from being based on LTWT to having become something nothing like it at all.
