Yeah, I’d suggest you go back and look at other Cool Wall Challenges. They’re an unique type of challenge with a different format than usual; the spreadsheet use is part of an established format that the host is following. And again, having “reviews” for each car at all is not part of the convention and actually way more than was expected of them; overall, I think they’re doing pretty well (other than changing the scoring calculation without explanation and not even responding to questions about it)
Come to think of it, I should probably do one of those “General Rules and Guidelines” posts like ARM and CSR has, I’ll get to it at some point.
