Understanding EV Calculation & Trends

The Expected Value (EV) is calculated using a sophisticated stratified sampling simulation. This involves:

  • Breaking down potential box contents into distinct groups (strata)
  • Running hundreds of thousands of simulated pack openings
  • Using an adaptive sampling process to ensure sufficient simulations per group for statistical accuracy
  • Calculating the weighted average value based on current market prices

Variance & Confidence

The **Standard Deviation (±)** represents the typical fluctuation you might see in the value of individual boxes due to pack-to-pack randomness. While the simulation provides an estimate of the *average* outcome (EV), actual results will vary.

EV Trend Analysis

Trend values reflect the change in Box EV since the last data update:

  • Green values indicate an increase.
  • Red values indicate a decrease.
  • Gray indicates no significant change.
