Some may show a gradual gain throughout the race, while others, which I refer to as drivers, wait until late in the race to make their move. This type of a runner pushes hard in the stretch passing many of the greyhounds and should never be underestimated. Determining the class of the race can be tough sometimes. This can depend on the stats you have available to you. Next, look for grade drops and how competitive the greyhound was in the higher grade.
Class tends to be a much stronger variable in higher-grade races.
This variable brings many arguments between handicappers. Some tend to place this factor at the top of the list, while others consider this lightly. Speaking for myself, I have found a strong correlation with the greyhounds having the fastest times generally will also be the class of the race. This factor can be gauged as seen in our stats. If a greyhound exhibits heart he shows the ability and determination to come back after finding trouble.
