Principle Minimize the number of sload/sstore needed. Since positions need to be iterated (to some extent), this minimisation is the easiest gas saving strategy. Definitions MIN_POSITIONS_RIGHT The minimum number of position which should be on the right of the current tick. If there are less than this amount of position, then the strategy needs to mint new ones. ex: 3 MIN_NUMBER_TO_ADD The number of positions to add to the right of the current tick, if there are less than MIN_POSITIONS_RIGHT
