You totally miss my point, let us not talking about raw or jpg, if I shoot 800 and can sell 480 images, or some one shoot 1500 and sell 480 images, which is better?
I believe you never shoot wedding with film before, and you do not know how the "system" works, recently digital photography are become popular in wedding day market, many players step into this field, people like you, does not doing it as a business, in term of business POV, many has failed, unable to recover initial investment, low performing in productivity, under price your service and products. Does not have constant flows of assignments, unable to perceive market requirement, etc.
Btw, to be honest with everyone, shoot wedding with film yield better profit in term of per dollar investment, and great time saving in postproduction.
