I would have to assume that the above poll was ment to be between numeric and descriptive stage notes. With that in mind, I would highly recommend that both styles be kept available. Remember that it is what the Driver wants to hear.
I myself used descriptive this weekend and found no issues or problems with the presentation or delivery of the information to my driver.
IMHO, both systems have a place in rally. Unless the orders reflected a 100% and only 100% take rate of one style or the other, cost not involved, I would continue to make both systems available.
