Snip. I read what you said here more carefully..........

Hang on! You are now saying that the high moved SW - exactly what I've been saying. That is movement against the main pattern of flow, isn't it? The definition of that is.....................?
dispersing by the 20th.
So no retrogression - just a single instance of a high moving into the
continent (a), with a new high (e) forming 1500 miles to the west. That
isn't retrogression. And, as I've said a few times before, the upper
pattern isn't conducive to retrogression.
Yes, that's your assertion. I could say the moon was made of green cheese, but it wouldn't be true without me providing evidence.
