While changing variants seems a bit unorthodox. I don't see the upside to Jerry saying what he thought unless he believed it to be true. We all know the foundation for accurate numbers is the best, most accurate variant. Both Ragozin and Thorograph want to make the most reliable numbers. If TG thought the track was changing it's their duty to make figures based on those changes. Their calculations. The numbers are the numbers why would it benefit them to say the track changed unless that's what their analysis showed?
