>> so if you entered 5 times and beat it by 1% four times and under performed by 4% on the fifth time, you come out to matching the S&P500... << that doesn't look right unless the length of time from the investment (not necessarily the start of the game) to the end of the game (in days) is the same for all 5 games. You have to adjust the raw data for the length of time for each investment and for the index change over that number of days. Measuring performance versus any index is not simple. And you might not count cash until it is invested. If the S&P is down 10%, and you are down 6%, would you call that beating the S&P by 4%? Or comparing 94% to 90%, beating it by 4.44%? If you seek a number that compares 2 levels of funds, it would be 4.44%. And if a player is up 10%, and the S&P is up 6%, would you call that beating the S&P by 4%? Or comparing 110% to 106%, beating it by 3.77%? If you seek a number that compares 2 levels of funds, it would be 4.44% in the declining example and 3.77% in the rising example.
