Did anyone guess correctly o the finishing times?
This is Daniel Metz am i supposed to say "these are all the procedures we went through" and list the procedures and what went wrong or just a list of steps in the final procedure
Good question Daniel. You are expected to have the most recent procedure that you will be using to test, measure and compare the speeds of several vehicles.
the discussions section of the report is where you mention the things you changed from earlier versions of the procedures and why you changed them.
