Actually it really does look threewavish (just my opinion/counting), and that would be a 5-3-5 flat (and a cute little expanded flat within it on a lower degree? not too sure now about how to count this triangle...):

(wave (iii) of circled C is not the shortest, no problem about it.)

I double checked it. You are right. Its a perfect ZigZag, with wave b being an abcde triangle. I did not revisit the lower timeframe again, so I missed it.
Thanks for the comment.

Bitte schön ! :)
