That means to me the game is currently at 20%.

Sorry to say, but this is completely wrong. Version e.g. 0.203.13 doesn't mean the game is 20% done, please visit https://semver.org/ to learn about Semantic Versioning.

On EA release (Feb 2021) the game was feature-wise about 75% and content-wise about 50% complete.
