This may not be of interest to many, but I have seen a few people post their progression of times in their signatures. I got interested in what mine would show so I dug through all the PBs I have posted over the years. I also added corrected times to see if they would tell me anything. Here is what I have:

My takeaways:
- I love negative DA
- I started modding much earlier that I remember (purchased Jan 09)
- I sure did not wait long in between headers and cam!
- Maggie torque helped the 60' a lot
- Huge ET drop with headers was magnified by outstanding DA
- It took of runs and dropping DA to get my best cam time
- Injured diff hurt 60' in 2012
- I want to see some negative DA before the tracks close for the season!
