On Ragozin Sheets, horses have become a little faster at all class levels over the last 10 to 12 years.

On Thoro-Graph Sheets, horses have become MUCH faster at all class levels over the last 10 to 12 years. Cheap claimers are now as fast as Great Hall of Famers.

However, all 3 figures have remained fairly consistent from class level to class level through time period to time period.

Thus, if you anchor the scales down with class pars -- all 3 of them will allow you a very comparison of todays horses with past horses at all class levels.
