i really dont understand the flexibility rating, on some racquets they feel very flexible, but they are given a high rating, what is up with this?

The stiffness rating is calculated be measuring upper hoop stiffness. As it does not take into account shaft and throat stiffness, a racquet with a stiff upper hoop may have a high rating even if it has a flexible shaft. We have been looking into ways of measuring zonal stiffness, but right now the industry standard is for measurements of upper hoop stiffness (as measured on a Babolat RDC machine).
A low stringbed stiffness created by an open string pattern or big grommet system etc. can also make a stiff racquet feel softer.
