There are many misleading charts and articles on playing harmonics on the saxophone, most of which are out of date as the design of Saxophones has changed over recent years.
Many sugested harmonic fingerings are based on using (for example) Selmer Mark 6 and 7 Saxophones which are no longer made.
I would highly recomend Saxophone Altissimo by Robert A Luckey, Ph.d.
