I could always tell when a set was done "at home" by first glance. The first hole is always the largest....most work done. As the job progressed you could tell guy was getting bored and just wanted to get them "done". Each port would become progressively less and less "worked" until the final hole looked like a quickie polish job...no need to even flow...even if the first hole WAS done properly.... which they never are as they ALWAYS only "open them up" at the accessible areas...
