No diss. I read that slot comment above you and went, "yep, yep, yep, makes sense. Man our standards are often dumb."
Laughed with joy at your comment, because I totally get how foreign this shit is to so many people. It's like if I walked up to a building engineer asking how they know that iron beam is safe for another 50 years via their skills and I'd just be like "......do what now?"
