I think nearly everyone counts a v terminal as two branches. I had not really ever thought of that as counting the scape, but I suppose it is. I just thought of it as a branch originating from the end of the scape?
"2. A terminal branch occurs at the top of a scape and may be arranged to form a
"V" (two branches), a "W" (three branches) or even four or more branches. A
terminal branch which does not divide at its terminus is counted as a single
branch. ALL terminal branches are counted which meet the required standard of
two or more buds per branch."
Edited to add the rule for counting branches from ADS.
