No, the basis for NASA's specs is parity in the mid field with mid prep cars. Haven't you been paying attention?? 
Apologies in advance if I'm taking one comment John made out of context, but the mid-pack comment seems really important?
The problem is that NASA seems confused in where and why they are seeking parity. Or maybe this is NASA seeking to subjectively please (since objective mid-pack is impossible) the most drivers at one time. If NASA aren't seeking parity at front of pack i.e. placing those who can win races on an even footing to fight it out for the podium, then I really don't understand what the intent is ........ ?
Chris, great argument & good points, but they are based on my
opinion. My opinion (on this) was not even communicated to NASA as the 'desire of the class', because it shouldn't be. I guess you have to know me to understand that I can be truly objective and would never push my personal agenda (
other than my desire to grow SM in NASA) in front of my duty. Yes I know, I'm weird.
So Chris, my comments were not taken out context, you (and others) just assumed that I'm a different person. Which is cool, you guys don't know me... But now you do, so please be sure of what you say or I will find you where you sleep.
So let me say again for the fifteenth friggn' time: NASAs National SM Director
DOES NOT MAKE THE RULES, they are the voice of the SM community. The NatDir makes suggestions (steers the conversation) and answers questions in attempt to keep SM the most competitive and largest class on the track. No personal agenda or allegiance should (or ever will with me) ever enter into it.
