The problematic part is that OP compares with 3% margin in Canada. OP knew that all along but decided to string everybody along without revealing this data point.
That’s how you put people off and keep questions from being answered going forward - keep pertinent data to yourself you knew all along, and don’t publish them until the end.
And don’t mention the idiot’s “you missed the part” even though he didn’t mention that fact at all.
I disagree with your conclusion. Yes, in hindsight it’s always clear what the most relevant information would have been. But the world, and this forum, is not always perfect, and that’s ok (at least for me).
