Do you make allowances for position at 400m?

For example, if a horse was 8th at the 400m, the time in the paper for the last 400m would be slower than the time ran by a horse which made up several lengths.

Also the time you calculated for first 1200m would be slower due to the horse being 8th at that mark.

If you made an allowance of say 0.5 lengths for every position behind the leader would that help your analysis become more accurate?

You could then adjust the times by about 0.15 seconds for every length.

Or is this making it all to complicated??
