As I sit back with popcorn and chuckle, for those too ignorant to know, you're trying to match whits with a professional performance engineer (Mutt) who quite possibly knows more at this stage on the subject and is far more conversant about performance, safety, and requirements, than some of those arguing with him ever will be in their sorry lifetimes.
You guys sure know how to pick 'em. I wouldn't argue with Mutt regarding performance, because I know from the outset, I'd lose. Some of you are simply too stupid to understand that, so have fun beating your head against the wall.
Personally I'll have fun watching Galaxy Flyer and Mutt wipe the floor with you, when they're done. (Not that they haven't, already...)
