Flag Over Porch (2915A) Die Cut Incision Styles

I'm having a hard time telling the difference in the incision styles A and B. I've referenced the excellent checklist by Hans van Gils (page 11):

Also referenced an old PNC3 Coil Line newsletter article (june 1998).

Both of these describe Style A as micro cut in the serpentine part with a smooth/clean cut in the top and bottom straight lines.

Both describe Style B as micro cut in all parts from the top to the bottom.

I can't tell what style my plate 97898 has. It's clean on the top only, with microcut through the bottom. Is this Style A even though it has only one clean cut?

Possibly a better picture:

StampsRx,
I do not know the answer to your question, but it is a wonderful model of stating the question clearly, reviewing your previous research efforts and citing the sources consulted, and providing excellent illustrations. It was refreshing! I hope you get an answer soon. Thanks.

Short answer is it is an A. Long answer when I have more time.

Thank you, John Becker. I appreciate your feedback!

Thank you, eyeonwall for your input!

Longer answer.
The description should say for one the entire height has ties while for the other there is a short section at the top and bottom that is bald when everything is properly aligned. In the case of your strip the die cutting is shifted down so the straight part that is normally split between the top and bottom shows entirely at the top so it is only bald at the top.
Now why did I say short section at the top and bottom rather than the more specific the straight part is bald and the serpentine part has ties? Because early one there was one die cutter that was not only bald in the straight part but also for a bit of the serpentine part at either the top or bottom (going by memory it was like one peak and half a valley or something like that). I can't recall if it was a 2915A or a 2915C. I'm not at home so Ican't just pull out some strips to say more precisely.
