If you'd like to contribute data points to this table, please use the following methodology:
Fill your command queue (e.g. with a few score brief commands) before casting so that the spell's timing begins on a server heartbeat. This will always be an even number.
Time the beginning of the cast on You prepare to cast Jogloran's Portal of Cheaper Travel and the end on solidifies with a satisfying thump. If you use Mushclient, you can see the timestamp for a line by hovering over it with your mouse.

If it's correct, it suggests the equation is very close to (within expected nuances of rounding etc that are likely involved in the actual code):
That predicts the next few steps in cast time reduction will be:
| ma.sp.mi bonus | Cast time (seconds) |
|---|---|
| 300 | 12 |
| 318 | 10 |
| 340 | 8 |
| 370 | 6 |

| 480 | 2 |
| 624 | 0 |
