Interesting observation about fretboard depiction and stroke direction, never thought that way!
I come to understand I should follow the down and up strokes religiously watching Ben’s tabs. And that it always starts with a downstroke unless it started with a half beat where you start with an upstroke.
I thought one of the reasons to do so was to “free up” the memory from thinking about stroke directions by making it a second nature, as then this pattern would become common for any song, to be able to focus only on notes particular to a song. But it would be interesting to do it differently like you mention to support the accent on a note.
