Because you cannot see the feeling of "dynamic/fluid tension," when one draws aims and shoots, unless your extremely critical.
I humbly, would rather you learn it from the best. Using his form as a guide and then analyzing it with help of his and John' s writings and vids as well. I have no problem posting it, but what I do is as they do, swing draw with no holding at full draw.
Besides if I post my form you will have an out, and be able to just write me off. You won't likely do that with Howard's. This way you will be much more likely to listen, learn, and try, as opposed to question, doubt, and ignore.
All that I have posted comes from their basics of tuning, and shooting. Someone that is having difficulties hitting with equipment that is decently close to tune has form issues, such as arrow clank off the riser that sometimes is and sometimes not there. Arrow too stiff only some of the time? of course not, your not pulling through the shot and you are not pulling it straight back, at the shot he string has to pull the arrow back in line causing the arrow to bank off the riser, equal and opposite reactions at work.
