✦ Synopsis

We re-analyse meson sector data from the CP-PACS collaboration's dynamical simulations [I]. Our analysis uses several different approaches, and compares the standard naive linear fit with the Adelaide Anzatz. We find that setting the scale using the J parameter gives remarkable agreement among data sets. Our predictions for the p and q5 masses have very small statistical errors, N 3 MeV, but the discrepancy between the different fitting approaches is N 40 MeV.
