1

Line up the piece that gets the notch.

Place a piece of decking on top of the previous piece. This means you'll have to lay decking as far as you possibly can so you can get as close as possible to the post.

Measure edge closest to the post

Measure from that board to the closest edge of the post. This will tell you how much wood to leave on the trailing edge.

Mark that measurement on your board

Mark the trailing edge of the board at that measurement. Mark it in two places roughly parallel to the edges of your post.
