Testarossa,

I see your point. Often the last 600m at Canterbury is run in 36.5 secs or 37 secs. It seems to be a slow finish. I've never been to Canterbury. Mooney Valley is similar, must be the short straight and turning track.

As a rule of thumb though, would you use less than 49.5% for the first part as fast for other tracks? While at Canterbury and Mooney Valley would you use less than 49%?

So more than 0.5% either side for most tracks, but 1% for Canterbury or Mooney Valley?
