Lab 4 skip is now viable for runs and can save anywhere from 10 to 40 seconds if done after lab 2, however the enemy used in the skip is very inconsistent with his movement. If a consistent method of getting him near the force field during the mecha arm fight is found i believe sub 8 could be possible. However if a entirely new method for lab 4 skip is found that doesnt involve fighting the mecha arm twice it could save upwards of 2 minutes.
