Adjust up or down if you want to be more aggressive or conservative.
My data shows you collect an average of 1.7 buffalo heads per spin. Adjust at your own discretion.
Notes
The average MHB feature payout is between 20 to 30 units, depending on how heavily you want to factor in outliers like hitting the major and grand.
The EV (expected value) is what you will make on average over many sessions. In the short term, expect large swings.
The potential loss assumes the meter goes all the way to 1800 (rather than the midpoint), the MHB feature pays $0 (which happens frequently), and the bleed rate along the way is 85%.
If you are having trouble dialing in precise numbers with the sliders, you can try zooming in or rotating your phone into landscape mode.
