This makes a lot of sense and explains it. Thank you. One way to avoid this would be some kind of an electronic shifter that would optimize (change 2-3-4 steps) the cassette cog if you jump from one chain ring to the other.
Never heard of "half step" before but a quick search pointed me to Sheldon Brown's write up which was, as usual, very helpful.
