I would look at this a confirmation the basics are good, so elimination of wondering about that may have some value to the OP
It is also not a bad thing as I would not be surprised if a lot of people ride with a close fit, but not optimum fit......
I found out my seat height was too low when i had a custom frame built and leg length did not match seat height....raised 2 cm and made a huge difference
