The Magnet Marshall is just a tool to show the relevant magnetic downforce created by the motor and/or magnets as compared to other cars. It’s not necessarily a real world example of the downforce you would get on our track as the braid depth is slightly different but its not meant to be a tool to tell you the exact downforce for our track. It’s a tool that is designed to give you a relative number compared to the other cars you are testing. When used this way it is highly relative.
