I used to think letting new guys handle trim was a good way to speed things up. One botched a baseboard so bad it took a full day to redo. Now I watch every cut like a hawk.
That real kicker is how a rushed job today means twice the work tomorrow. Seen it a dozen times where trying to save an hour burns a whole day fixing their cuts. The best shortcut is showing them the right way on some scrap first, even if it feels slow. Lets them build the skill without wrecking the actual piece.
