Pick one reality. Put your Insight mods against the template. But if you insist on "putting no more into it than I see done here", then post a good profile pic of your Insight so we can. If you won't even do that, leave. Go away. We'll call Darin in to delete all your spammy looking book links.
I'd rather they not be spam, though. Because you do really good work. You improved the first gen Insight, but you're pissed off that other people have also put time into aero work. Can't we all just get along? You're doing great work, why the need to trash other work? Ecomodder is a place to share so that everyone doesn't have to reinvent the wheel. A lot of good work has been done already, and a lot of it has been shared here. You've been adding to that.
Really, though- look at your Insight pic that didn't meet the template, and look at your personal Insight with your own spoiler. It looks like you wanted the Insight to meet the template.

Happy to talk about the Insight, even though it's a typical red herring to the argument.
1. The Insight has a sharper downwards rear angle than The Template, and so according to Aerohead, it should have separated flow across the hatch.
2. Of course it doesn't - The Template cannot be used to predict separated / attached flow.
3. According to Aerohead, rear spoilers 'reach up' to separated flow. Of course, that applies only in very old cars with separated flow on the back, not a modern shaped car like the Insight.
4. So, according to Aerohead's theories, the spoiler on the back of the Insight cannot work - its rear edge is no higher than the standard rear lip.
5. But of course, it does work - it's operating in attached flow. (Just as with the recent, properly measured, data on the Prius and its trialled rear lip*.) It works by changing attached flow direction, not creating flow attachment.
6. If I'd followed the theories of Aerohead and The Template,
the spoiler would look nothing like it does. A spoiler made to his theory of reaching up would also have increased drag with its larger wake.

You're quite wrong. I am - in your words - 'trashing'
incorrect theories and misleading advice.
Would you rather people were continually led astray?
* testing that of course Aerohead immediately denigrated.
