• 2019-2020 formula for the normal score
• Current formula for racing (tweaking values to make the resulting number bigger, so easier manipulation for overall ranking)
• Current formula for survivor (tweaking values to make the resulting number bigger, so easier manipulation for overall ranking)
• Current formula for defilante (tweaking values to make the resulting number bigger, so easier manipulation for overall ranking)
