Official response I got after asking directly. Hope this puts some of us chronic Del Taco-ers at ease.

I remember years ago working at tacobell there was on official weight that tacos were suppose to weigh and periodically manager/corporate would come in and spot check us. Is this the case with Del taco. I feel like sometimes the Big del taco is a crap ton of meat and other times it's skimpier than a Taco Bell taco. Do you guys often experience these inconsistencies?
