Even many of the best respected skate techs have sometimes manage shops where not all the techs were equally good, or which were not at rink facilities. I've noticed that too. Each also limits what they do. E.g., some won't do the types of boot and blade modifications that I've learned work best for me. Skaters also sometimes get used to the specific ways a given professional does things, and only perform best with their work.
Many people like me who have far less experience and knowledge can adjust our blades and boots better, for ourselves, than the most respected professionals, because we learn what we specifically need. But we can't all learn to do everything for ourselves, just like we can't all repair our own vehicles, build and repair our own homes, or meet our own medical needs.
Plus, athletes constantly train their bodies to work differently, which changes what they need over time.
With all these issues, it isn't surprising that even the best professionals in any field, can't please everyone.
There is always some trial and error guesswork. All professionals need feedback on what you want and need. If you don't provide that feedback, to even the best skate tech, coach, physical trainer, teacher, home builder, etc., can't do as well. Of course some professionals don't encourage feedback, and therefore please fewer customers, and never get better.
After Kaitsu moves the blades to the center, I hope he explains why, and asks her to tell him if she still wants something changed.
