Dyno sheet for each year?

[jnybbad]

Do I need to get a Dyno every year I race in the same class, ST3? My car is unchanged!

Page 14 of the ST Rules:

Certified Dyno reports are potentially valid for up to a maximum of three years (provided that no changes have been made to the vehicle that would alter Dyno readings). However, at his/her discretion, a NASA ST Leader may require an updated certified Dyno report (at the driver/owner’s expense) after one year from the date of the previous report.
