TIL I've been cutting dados wrong for 10 years

I was over at a buddy's shop last weekend watching him knock out some bookshelves and realized he never flips his board over when cutting a dado stack. I always just ran it through once and called it good, but he flips it and runs it twice to keep the cut clean on both sides. That explained why I've been fighting tearout on half my jobs, anyone else learn something basic way later than they should have?

And it's amazing how something that simple can make such a big difference in the final product. I had a similar moment a few years back when a carpenter I sub for showed me the same trick. Sometimes it's the little things we overlook that save us the most grief.
