Message	But I hope that a minor difference in theoretical vs. actual circumferences won't lead to a big difference. For the record, I feel that the tach is accurate enough for my needs (I occasionally autocross, but I'm not a 1/4 mile junky). I just thought it would be an interesting discussion topic to see what other folks have experienced with their tach accuracy. Thanks! Dave
