This would probably get way out of hand with resubmitting your mix, but a recall is "real world". (This was mentioned earlier)
A second submission deadline after the critiques to see if the mixer can deliver what the "clients" want.
I'm just thinking outloud. With so many different opinions, how would one make everyone happy? What if a handful of guys were the "client"... The final word after critiques that judge recalls? Each guy gets like 5 mixers to work with.
Once again, just thinking outloud because you asked. Big can of worms, I know.
