directors will bump someone up or ask them to move up if they feel they are in the wrong class. Some tracks have explicit rules where you have to bump up if you have won a certain number of races in one class. Often apparent sandbagging is not intentional, and is actually the result of someone sincerely misjudging their own skill level. This can happen if someone is new to the track and doesn't know their level in comparison to others, or if they have not competed for some time and are not sure they can immediately regain their previous skill level.
