The Melinda time is a term used to refer a time higher than the current bold time that theoretically could be obtained, but would require extreme luck and/or skill - often both - to obtain. They are almost always caused by the use of random elements.
Requires extreme luck with random force floors near the end: Chip must push the block on them, and it must stay there long enough for him to open the red lock and move either DL or DR to safety. Whether 717 or a lower time is reached
Requires an alternate path that is very risky because of the high concentration of blobs, and for blobs to delay a teeth from moving towards Chip on at least two occasions so that it does not interfere with his moves.
The Melinda time is difficult to calculate because of the large amount of random force floors and the erratic pattern of the toggle walls. When the bold was 476, the time was calculated as 488, but improvements in the non-random area of the level have left this total indefinite.
