Simulating 10,000 games for each training regiment and with the assumption that total stats is what makes you win, the best average is to train Easy Medium with 201 total stats on average. However, training Easy Easy shows up as 200 total. Given the decreased chance of missing a match, I would say only train Easy. The worst performance was from Hard Hard with total of 182. Training Harder difficulties then Easier difficulties led to a performance decrease as opposed to Easier then Harder. After the Massage oil, the worst outcome is from Easy Easy. Even Hard Hard gives an increase of 10.5%. The best case scenario is to train Medium Medium with 245.11, a 22.5% increase in stats over Easy Easy.
But ultimately, it is better to grab the treadmill early as 6 points per day with no chance of injury. It is like training Medium Medium with no drawbacks. Easily the best choice, ASSUMING total stats is what determines victor.
Initial Battle: I grab the ball and head towards the opponent's goal. The opponent says "Screw that" and heads towards mine. I shoot.... THE BALL TELEPORTS TO MY OPPONENT!!! He shoots and scores.
Luckily, the game ended in a tie. Me:1 Opponent:4
