While the timing isn't SUPER scientific because you're able to move before the screen actually fades in all the way after a death, this video shows that there's a fair potential for death abuse in at least some levels.

According to other research, the time between death and when you can take control is 2.233 seconds.

Here on Vertigo if you can catch the first spike ball cycle (which appears to only be possible with the early start you get from dying) you can make the first cycle of the platform, which is approximately 5 seconds faster than waiting for the second cycle. The exact time save shown in this video is 4.917 seconds.

This means if you can kill yourself in 2.684 seconds or less, you're technically better off killing yourself here and getting the first cycle of the spike balls (assuming you can get it every time).

I was easily able to get a death in under 2 seconds, meaning you could likely get about 3/4ths of a second saved with death abuse.

While this wouldn't be useful at all for full game or full world runs it may be useful for anyone who would want to do IL runs for Vertigo.
