Community analysis reverse-engineers Max x5 and Max x20 Claude usage limits Anthropic won't publish

A community investigator reverse-engineered how Claude Max x5 and Max x20 subscription plans compute usage after Anthropic declined to publish the methodology. The analysis identified a consistent set of point values that satisfy a "100x" principle across observed usage patterns. The findings allow Max subscribers to estimate remaining daily capacity more accurately than Anthropic's official guidance permits.
