Booster progression: evidence and testing method

This page previously described illustrative figures as empirical benchmarks. No reproducible gameplay dataset was attached, so those results, performance grades and animation-threshold claims have been withdrawn. We have not established a gameplay soft cap at 85, 90 or 95.

What a valid calculation record needs

1. Exact card ID and version, source date, base attributes and maximum level.
2. Training allocation by category and its actual point cost, compared with the available budget.
3. Manager, booster, level and condition assumptions, including which effects the tool models.
4. Input data, calculation version and output attributes so another person can reproduce the result.
5. Comparison with the values displayed for the same card in the game. Differences must be recorded, not silently adjusted.

Calculated stats are not gameplay results

A higher calculated attribute does not prove a higher win rate or that a particular animation activates. Such conclusions require controlled observations, sample size, platform and game version, a comparison condition and a discussion of uncertainty.

Try a comparison without treating it as a benchmark

Choose two public card records, keep the assumptions consistent and inspect their attributes. Check the result in the game before spending resources. A future measured study must publish its method and evidence before adding conclusions here.
