Lots of emotion and exertion in those photos Dean, well done!
A good demonstration of a need for bursts is any sport that doesn't necessarily have a predictable peak of action, like you show here. Same goes for Wildlife where in 80% of cases one has no idea where and when a peak of action will occur!
