Anyways, I can see what you are saying in that it will show some sort of empirical data. However, I don't think it produces any meaningful data. While you would know that it got faster/slower/the same, it doesn't tell you HOW, and therefore, really doesn't tell you anything. A track result such as my own, and a dyno result can tell you what you gained with a measurement that most people can relate to. I never do 2nd gear 20-80 races so that is in no way relevant to me. Losing .1 in 2nd gear from 20-80 doesn't tell me how much power I gained, or how much ET I will dropped. I do understand 1/4 mile times, so that IS relevant to me. I hope that better explains it. But as always, to each his own.

20-80 doesn't tell you how much power you gained but it does tell you what the power did, isn't that the point.
20-80 in second gear takes out many variables there would be in any kind of acceleration test while still making the entire curve relevent.
