Which would be an example of conventional milling.
No, it would be a climb cut if fed from the back. Actually, it would be a climb throw when the blade bit in.

True that all of the cutting is in the 180 degree arc on the leading half of the end mill. but it seems to me that the cutter is conventional milling as the cutting edge enters the arc and climb milling as it exits the arc with a transition in the middle. Maybe that’s why it’s called slotting instead of conventional or climbing? Those terms do apply when the sides of the slot are being cleaned up or the slot is being enlarged with an end mill smaller than slot width.Not strictly true ! It is conventional milling. The cutting is taking place in the direction that the cutter is moving, in the arc formed by the diameter of the cutter.
I agree that if you want an accurate width slot then clean up the sides with a smaller cutter.

The tool, in this scenario that is unimportant as one side will be climbing and one side conventional milling at all times regardless of feed direction.I the diagram above, when you say "feed direction" are you feeding the stock or feeding the tool?
This page discusses it well and also discusses the importance of the application.

The Harvey tool illustrations pretty much explain the entire concept. What could be more simple to understand?
