To easily gain stat points, do the following. Every time you complete a mid-week challenge that gives you the type of stat points desired (for example, Concentration, Power), do not return to the calendar after completing the challenge. Instead, choose "Restart Event" from the menu, and replay the event you just completed. The stat points that you earn from completing the challenge will accumulate. For example, 500 Power points and 200 Concentration points multiplied by how many times you complete that specific challenge. When you are done repeating this process, just choose "Return to Calendar." The calendar will show that you completed the challenge and from there you can go to the Pro Shop and use all the stat points you earned. This works with all challenges (Putting Frenzy, Shooting Gallery, etc.).
