Honest question: how often do you actually get perfect margins?

I see all these Instagram posts with "perfect margins" and I'm like... really? Because I feel like I'm doing well if I get 80% of my margins perfect. Am I just bad at this or is everyone else exaggerating? I know what perfect looks like, but in a real patient with real saliva and real time constraints, how often does it actually happen? Be honest. I need to know if I'm the only one struggling with this.
