My old load calculation chart is a relic from a simpler time

I was sorting through my garage and found a faded load calculation chart from when I first started. Back then, we'd sit at the job site with a pencil and scratch paper, adding up watts and applying demand factors by hand. It felt solid, like you really knew what was going on in the walls. Now, everyone just uses an app on their phone that does it all in a blink. I get that it's faster and probably cuts down on mistakes, but it makes me a bit confused. Are we just trusting the screen without knowing the why anymore? I miss watching my old boss sketch it out and explain each part. Sometimes I worry that skill is just fading away with the paper.

Make apprentices do it the old way for their first six months, then let them use the app. They need to feel that confusion you're talking about to really get it. My guy has to sketch a one-line diagram by hand before he's allowed to open the software. It's slower, but he won't get lost when his tablet dies on site.

Lol my old chart is probably covered in coffee stains and math I can't even read anymore. It's like finding a map to a treasure you already dug up with a metal detector.

Honestly I used to feel the exact same way! But seeing an app catch a major code violation I missed on paper totally changed my mind.

Actually that's a fair point about apps helping spot mistakes. But isn't the real skill still knowing the code book itself? The app is just a tool, it doesn't replace understanding why something is wrong. Relying too much on software might mean you miss the deeper reasoning behind the rules. What happens when the app glitches or there's no signal? You still need to be the one who knows what's right.
