BUT
b) your body structure is also important
everybody is different. some of my students can stand in sei ping ma right away, on the other hand it takes months or even years to others (i eg. still have troubles a bit with my right leg). if they force the feet parallel, they would just hurt themselves, especially the knees.
one of the reasons of the "stance training" (jaat ma) is opening the hips, than everything, including toes forward, is easier. it takes time. that is why the oldtimers said: "3 years for stance training"
btw., in our lineage we never sit in sei ping ma "thigs parallel", just in "half sei ping ma" in tsk. we always have thigs little higher than parallel.
i like the profound analysis of Shaolin Warrior (thnx a lot), i also agree with Ho sifu - good sifu teaches a student not to move like he moves, but a student should move. everybody's Hung Kyun will be slightly different.
also, we should not forget that in a stress situation one looses cca. 25%, so we should always strive for our best.
my 2 cents, all the best, enjoy your daily horse
here is an excellent example of sai ping ma
