Beneficial 'class' ratings?

Flemington: Only a dead 4 but still a bookies benefit. There were more 'class' bandits running around than you could poke a stick at.

r1 ORBITING BELLE 11.20
r2 BERTONIC 12.80
r3 ROSE SYRAH 7.40
r4 LEICA LARRIKIN 47.30 [a maiden in a $100k race]
r5 FIGURE OF SPEECH 28.20
r6 GOLD SALUTE 10.90
r7 GRAN SASSO 2.70 [wacko, finally a top rating favorite home]
r8 PACINO 4.70 [wacko again, we are all getting rich, up there in the ratings]

Class ratings are a total waste of time [regardless of source] in my book. They are a stupid way of influencing the selection of winning horses [only in MHO though]. Does the race suit? Does the pace suit? Does the barrier, conditions and distance really suit? Should the horse even be in the race at this time? Class rating will not tell anybody those 3 simple things as the Flemington results show.
