very accurate, look it up on the net, the only problem is you have to take into account all other factors such as wind and stuff, so in my opinion, great for time and distance such as 3/4mile and excellent when checking out new mods because you can do a before and after run, starting in using just second gear to make it fair. but not the best to fiqure out HP.
