Consider this. Yes form is nice, and if you have not heard these words "good, better, best" than let me put them out there for you. Master Chunyi Lin says there is no right or wrong way of doing forms, only good, better, best. It certainly applies here. But I would like to add something to this, love and intention. Master Chunyi Lin says It is your love energy you are transmitting, and we all agree. I also feel the intention within your thought, or mind that acts as a focussing beam for that love energy also counts. It is what you intend to have happen and the love with which you do it, not the exactness of the form. So, put out your sword fingers as best you can, the energy will do the rest.Two people making the same bread, if all else is equal, will get different results.
...The difference is love and intention.
Well, I hope this helps somehow,
