Before/After gain Angle

Look at the first two calls of the horse's next-to-last race and note if the horse gained both running positions and lengths between the first and second calls. Then look at the last two calls of the most recent race. The horse must also show a gain in running positon and lengths between the stretch call and the finish. The horse must not have finished higher than third and today's race must not be higher in class than the class of the horse's next to last race. Bet if the odds are 5-1 or higher if the horse is in the same class or 10-1 in a higher class.
