Black Caviar is rannked thrid because of 2 columns.

See form guide below for those interested.

It as a rating of 1 for CF and 1 for TIM. The two above it have 40+ in both these columns. This is where understanding what the neural's are trying to measure can help greatly. CF is measuring runs this preparation. Black caviar is returning from a spell thus 1. Personally I think you need to check the first up form here and make adjustments. Black Caviar is 4 from 4 first up. TIM on the other hand is a hit and miss variable that I can't understand when they update and when they don't. I suggest its times this prep as well though.

If you want those not affected by a spell use the following settings only.
CP, JA, JT, TA, BP, CRS, DIS, $,

Using these and setting the others to 0 Black Caviar is the top rater with 290. next closest is 179.

Hope that exaplins it.

The NR value is just a combination of all the other variables (added up).
