Direct answer

Gym growth and stronger leagues are confirmed progression systems. Because Coach a Fighter is in Early Beta, use the current server for prices, benefits, and qualification requirements, then record the values with an update date before comparing upgrades.

Upgrade decision checklist

  • Read the current cost and stated benefit in your server.
  • Keep enough cash for the next required match or preparation step.
  • Upgrade the bottleneck you can identify, not the most expensive option by default.
  • Recheck requirements after any server shutdown or update.

Why version labels matter

The developer warns that progress and balancing may change. A useful table must therefore include the update label and capture date next to every price and requirement.

Map the current upgrade path

  • Capture each visible gym upgrade name and its stated benefit.
  • Record the current price before purchasing.
  • Keep locked upgrades in the table with their displayed requirement.
  • Start a new version when Update 2 or a later title changes the values.

Choose the next bottleneck

The next useful upgrade is the one tied to a visible limitation you can document. Avoid ranking upgrades solely by price or assuming that the last unlocked option must be optimal.

League readiness checklist

  • Confirm the current league requirement in the live interface.
  • Keep the required cash outside the experimental spending budget.
  • Record the roster and gym state used for the qualifying attempt.
  • Capture the promotion or failure result before publishing a rule.

Build a versioned progression table

A trustworthy league table needs the league name, requirement, entry cost, reward, capture date, and update title. Blank fields are better than values copied from a different beta version.
