[QUOTE="cobraCMDR, post: 4013701, member: 25210"] Everytime I see someone post a dyno chart I always think the following. Regardless of the fact that they "forgot" to mention mods lets forget about this for a minute. They posted ONE graph. That is a sample size of ONE from a statistical sense, which means according to the Basien (SP) estimator theory this means you are about 33 % confidence in your improvement. Now take say 3 samples or 3 dyno pulls or 3 quarter mile times you have about 66 % confidence in your improvement. If you want to be 95 % confident in your improvement you need to take 11 samples. My point is too many times people post up their single highest dyno chart or track time and everone goes ooo ahhh look. The reality is people want to know realistic numbers are. I'm not saying these are not realistic numbers, nor am I saying lets all become statisticians. All I'm saying is vendors, tuners, people lets be a little more accurate and take the average of 3 when testing for improvements. Evolution please feel free to post your 3 best quarter mile times from you track trip this weekend. I would be interested to see the results. [/QUOTE]
