I have contacted Darline Hobock and asked her if she has been able to accumulate any data related to F-16's, Taipan 4.9's or Stealths racing open class. I will let you know what she says, but I sincerely doubt that she has much data at this point.
If you want ratings changed, you have to make sure regatta results are sent to her.
Darline has now told me (March 11, 2005):
"I have been accumulating data on the Taipan 4.9 sailed as F16 and on others from races abroad. I, too, think the F16 rating is too high. Preliminary race analysis agrees."
So there you have it. The writing is on the wall for a rating change. I guess this is for better or for worse, depending upon who you are talking to.
