Assessed contributions and expected value in MMA

Basic guide to assess whether a fee has real value before betting.

1) Implicit probability of a decimal fee

In decimal format, the implied probability is calculated as 1 / quota. If the quota is 2.00, The implicit probability is 50%.

Formula: Implicit probability = 1 / quota

2) What is the expected value (VV)

The expected value estimates the average gain or loss of a long-term bet. A bet has value if your estimated probability is greater than the implied share.

Formula per unit wagered: EV = (p × quota) - 1

Where p is your estimated real probability (between 0 and 1).

3) Practical example

If a quota is 2.30, its implicit probability is 43.48%. If you estimate the fighter wins 48% of the time, then Ev = (0.48 × 2.30) - 1 = 0.104. That's equivalent to +10.4% per unit in expectation.

4) Where the gambler error usually is

Confused high quota with “value” automatically.
Do not adjust the estimation by matching styles.
Ignoring the margin of the house.
Overlay the last combat (recense bias).

5) Simple operating rule

Before betting, define a probability of your own. If you can't justify it with style, rhythm and defense data, there is no "pepper." No estimate, no "ev.
