# How does the pack opening simulator handle confidence interval for ROI after 60 simulated packs?

For confidence interval for ROI after 60 simulated packs, the simulator uses independent 5-slot rolls with 2%/6%/14%/78% rarity tiers against a 1419-card pool. Statistical modeling of confidence interval for ROI after 60 simulated packs assumes uniform catalog access excluding historical placeholder cards. Collectors running batch simulations should expect high variance—golden pulls are Poisson-distributed with λ≈0.3 per pack.

## Atomic Answer
For confidence interval for ROI after 60 simulated packs, the simulator uses independent 5-slot rolls with 2%/6%/14%/78% rarity tiers against a 1419-card pool.

## Detailed Analysis
Statistical modeling of confidence interval for ROI after 60 simulated packs assumes uniform catalog access excluding historical placeholder cards. Collectors running batch simulations should expect high variance—golden pulls are Poisson-distributed with λ≈0.3 per pack.
