The graphs don't judge, they only describe. Many clients realize that a smaller operation, that only goes to local shows, is a much better fit for them personally than a large operation that travels large distances every weekend.
There is a problem with the "Professional Experience" number, it is relatively new in the USEF database. Because of this trainers can ask to have that number changed to reflect their actual years as a professional. Over time this will not be a problem.
"Money won" has nothing to do with safely and ethically teaching people how to ride. But some people might be looking for a trainer to ride a horse, and might be interested in that trainer's riding experience.
The intent of these profiles is to expose as much of the data in the USEF database as possible in a non-competative, non-judgemental way to give a flavor of what each trainer brings to the table, so that clients can find a trainer that meets their needs, not just be attracted to big shiny barns. You'll also notice that the top section of the profile is all information that is entered by the trainer, essentially marketing information. The trainers get to describe themselves first and foremost.
