This is a geometric mean not the arithmetic rate of 4% ( r = ( 1 + 0.2 ⋅ 1.0 ) 0.6 ⋅ ( 1 − 0.2 ⋅ 1.0 ) 0. Using the Kelly criterion and based on the odds in the experiment (ignoring the cap of $250 and the finite duration of the test), the right approach would be to bet 20% of one's bankroll on each toss of the coin, which works out to a 2.034% average gain each round. 18 of the 61 participants bet everything on one toss, while two-thirds gambled on tails at some stage in the experiment.
