Took me 5 years to realize I was wrapping electrical tape backwards

Ngl, I've been an electrician for over a decade. Last month I was showing a new guy how to splice a junction box and he stopped me. Said 'hey, you're pulling the tape the wrong way around the wires.' I told him it didn't matter as long as it stuck. He showed me how stretching it at an angle gives way better tension and seals tighter. I tried it and honestly my last 5 years of taped joints are all garbage in comparison. Has anyone else had a basic skill they were doing completely wrong for years without knowing?

That "stretching it at an angle" trick actually saved my air conditioner from a leaky duct tape disaster.
