As accuracy seems a problem, is their any point in sectionals except for them often leading us up a garden path?

They seem like a good idea on the mostly small US dirt tracks and play a big part in handicapping there, but in OZ with the rails all over the show and the track times often different depending on very small differences in 'good' track condt. [even the length of the grass would make a difference], track records are often set in very middle of the road races.
