I'm shaking my head over here at the irony. I've understood the challenge NHRA has been up against when establishing new classes and their respective indexes. With all the new technology and power adders, it's probably not as easy to set an index as most think. Hell, Bruno struggled with DD/AT for quite a while in the beginning. It wasn't until he really figured out the combo that people complained the index was too soft. When H, I, J Dragster were introduced there were all kinds of different thoughts and opinions as to what the indexes should be.
The point I'm making is this. With new technology and power adders being introduced into Comp, it makes a little sense that coming up with a proper index is a challenge. But for the super stock hemi cars? There is literally, 51 years worth of run data to gather and implement a fair index! This is not a new type of car with new technology where nobody really knows the potential it may have. These cars have been refined as hell over the years.
They could have just pulled the last five years worth of run data from the Hemi Challenge at Indy and used it as a baseline. Sure, the weather at Indy in August/September is worse than the weather at Gainesville in March or Pomona in February, but at least they would have been analyzing runs from all the heavy hitters who all have their shit set on kill. Could have started with these runs as their baseline and then tweaked from there.
