Calling weighing wrong is fine and a personal opinion.
The truth is that it should just realistically be the rule now. We aren’t in a magical world where it isn’t happening to the vast majority of vintage packs. Selling “unweighed loose” vintage boosters is unethical to me at this point.
I really wouldn’t even purchase a loose pack anymore unless it was weighed high or low
We have very reputable people like Rusty selling unweighed packs from freshly cracked boxes, but even that is quite uncomfortable as it leaves the door open for others to crack a box and claim to sell all the packs unweighed while weighing them off camera.
Tl;dr I think all vintage packs should just be sold as heavy or light at this point as pretending you have the 1:3 chance from the 90s is an outright lie
