We've had conversations where the Tae Geuk forms come up, and sloppy and unfocused usually come up at some point in relation to the short stances and the (probably) purposeful lack of kime.
Are you talking about the Taeguek poomsae performances you've seen in your area? The sloppy I can understand, because up until about 12 or 13 years ago, there was no emphasis or attention given to poomsae. They were just sort of there and no one cared how you did them. But with the opening up of the Kukkiwon Instructor Course as well as the creation of the WTF World Poomsae Championships a few years after that, poomsae is now receiving a lot of attention.
The walking stances come directly from GM LEE Won Kuk, who learned them from FUNAKOSHI Gichin and Yoshitaka Sensei.
