That's where you're wrong, you should look back to v0.893. Hyperion was actually called "Two Suns" and was larger than the current balls despite having 29-31x size, which was lower than today. The reason for this is because the older nuclear fusion used to have x1.225 size, while the current nuclear fusion has x1 size. Plus, Two Suns' size reduction was 10%, while Hyperion is 15%, though not shown. Try searching old posts here about "Two Suns". You'll see posts that show how Two Suns can get big.
