Not surprising that the 2CV is in and the Ferrari's are out... The question is though: Is Tamara having fun? How is the Pagoda keeping up?
And I know, regularities are NOT easy... After training my driver for a long time, we can now do regularities within +/- a couple of seconds, and occasionally score 0! The trick is to get the driver to drive on RPM instead of speed, and for him to count the number of seconds (in his head) that his RPM is lower than target, and to then exceed the RPM's for the same time after the slow down (the turn, or the hairpin, whatever). That way you keep your average speed about the same, and the corrections he needs to make are small.
Key is: get the right route first. If you drive the wrong way, your time becomes the least of your problems.
