The idea is that the larger the story is, the more uncertainty there is around it and the less accurate the estimate will be. Using Fibonacci series numbers, we estimate points based on number of hours it would take a lead engineer to do something. It aids in estimating the effort required for agile development tasks. Reduce overhead by removing one of them: estimation. The idea is simple enough. Planning Poker is done with story points, ideal days, or any other estimating units.
