Harvesting: Logging / Notch Position

Using the same principles as mining and fishing, here are the results in the same way I have been fishing.

Using the wonderful depth gauge notch gauge above here are my results so far. Please note as with fishing and logging you will still harvest items that are not necessarily what you are targeting, just more likely to get what you want.
