Hi Paul,
Yep the total cost of those 169 trifectas would have been $20,280 for a $1 and the return would have been $14968.00 for a loss of $5312.00.
It's all raw data at the moment as those races are from 5 different states, including all distances and surfaces.

You obviously wouldn't bet on every one of those races. Like yourself, I am in the process of narrowing down the qualifying races and how I will bet them.
From the small sample I have recorded, I have noticed the ratings do better @ Melbourne & Adelaide especially over 1200m & 1400m.
It's all work in progress
