Whoah! That would feel weird. We've always been taught that it's 50:50. No bias towards attacking or defensive footwork. No bias towards front or rear leg.
I guess it's the nature of competition differences between ITF and WTF. In ITF more strikes landing scores more (so having a light/quick front foot helps), in WTF only powerful strikes score (so you don't want to have a bias to only be able to use one leg powerfully).
Close - I find that its an inherant trait. When I trained ITF, I learnt 70% on the back leg, but it wasnt for that purpose. I do, however, know exactly how You came to figure that conclusion, since I used to hold it as well.
The reason is because Traditionally, Youd start with the Hands, then follow with the Feet. Even if it was just moving the Hand Positions. Having weight on the Back Leg helps chamber Kinetic Energy, or something like that. It isnt as fast, but it hits hard and pushes hard. It also makes it easy for you to switch to a forward stance at a moments notice.
In ITF Sparring, People tend to develop a variation of a 'Sparring Stance', which in many ways resemble WTF Sparring Stances. The biggest difference is, WTF Competitions tend to lead with the legs. So do ITF Competitions. But if Youre using a back-foot-weighted backstance, more than likely in a not-point-based-bout, try leading with the Hands, then using the Rear Leg. It makes sense to Me, anyway.
I guess its similar to how some Boxers weight down their front foot, so as to lunge easier, only in reverse. A Boxer would shuffle, a TKD Practitioner would step out into a different stance.
Additionally, WTF Sparring tends to involve trickier footwork, where these more weighted stances are meant for simpler movement. The same goes for ITF Sparring of course, but in a different way.
Its 1:43am, and if that doesnt make sense, Ill gladly reply again tomorrow, with what will probably be one short sentence thatll make a ton more sense than all that
