Mathematical Formula Corrections

2025-08-24

Fixed critical mathematical errors in the bankroll and confidence calculations:

  • Required Bankroll Formula: Corrected from n = (z×σ/μ)² to n = (z×σ/(μ + case_price))²
  • Confidence Calculation: Added missing bankroll term in z-score calculation
  • Mathematics Documentation: Updated the Mathematics page with correct formulas and detailed derivations

These fixes ensure that the bankruptcy avoidance model is mathematically consistent and provides accurate bankroll recommendations and confidence calculations.

New Cases & Items Added

2025-08-24

Expanded the database with additional case collections:

  • Control Collection - New case collection with updated market prices
  • Rising Sun Collection - Community case with regional variants
  • St. Marc Collection - Premium case collection
  • Map Collections: 2021 Dust2, Mirage, and Vertigo collections

All new cases include accurate probability distributions, updated market pricing, and full integration with the bankroll calculation system.

New Items List & Navbar Tab

26/06/2025

Added a dedicated Items page that lists every item along with its maximum market price, the most profitable case to open, and that case's Net EV. The table supports sorting (defaulting to highest max price) and colour-codes item names by rarity.

An Items tab has also been added to the main navigation bar (left of FAQ) for quick access.

Item Page – Net EV Per Case & Sorting

2025-08-24

The item detail view now displays the Net Expected Value of every case that can drop the item. Lists are pre-sorted from highest to lowest Net EV, and the new column header lets you click to toggle sorting direction.

Fixed Bankroll Variance Calculation

2025-08-24

Resolved an issue where individual item probabilities were not distributed correctly inside each rarity bucket. This caused the variance (and therefore recommended bankroll) to be overstated. Results and bankroll suggestions should now be noticeably lower and more accurate.

Added Float Value Caps

2025-08-24

Implemented float value restrictions to match in-game limitations:

  • All gloves: 0.06 - 0.8
  • Doppler/Fade knives: 0.0 - 0.08
  • Rust coat family knives: 0.4 - 1.0
  • Other knife finishes: 0.0 - 0.8

This change ensures more accurate price calculations based on wear values.
