I actually enjoy doing the Form usually.
Making money is secondary.
If making money was important , I would get a day job.
Of course , losing money is bad , but breaking even is acceptable.

The reason I tend to concentrate on higher Class Races , is because it is easier to compare animals that have often raced against each other , but mainly because all their characteristics are available to see.
The Lower Class Races often have inconsistent animals where Form is much less of a guide to the winning chances.
