// Changed to the four complicated lines because the previous Sink effect fails to fully inflate the |

// Masterball. |
|
| 58 |
// Current function inflates and deflates much more as H is at the extremes (close to 0 and inf) |

Improve the Sink effect so that at extreme strengths (close to 0 and infinity) it inflates and deflates more.
Reason: previous version failed to fully inflate the Masterball to a nice sphere.
