I assure you it takes more effort and energy to leopard crawl a distance than to run it. There is a reason we bipeds shift to walking and running instead of crawling our whole lives... it expends less energy for distance travelled.
Again,I suggest you go out and try to run 30 ft and then leopard crawl 30 feet yourself...
Past that I'm done arguing the semantics of calorie burning.
But I agree with your statement about the importance of adaptablity.
