Applied some of this a few days ago. Yeah so basically:
-Beginners love to do things that make limbs clash.
-Slow speed = more chances of clashing.
-Moving around the opponent = less chances of clashing.
But I am starting to see how point sparring can develop bad habits. I love the kata of Shotokan, just not the tournament-style sparring.
It shouldn't cause bad habits.
Train free sparring. Compete in point sparring.
If all your training is free sparring bad habits shouldn't develop and competing in point sparring is an easy adjustment.
