Why is my particle lifetime always 1s longer?

Hey there!

I made a little beam particle emitter for a laser shot I wanna use.
Since I want the laser to be very quick I set the lifetime to <1s but it always exists for pretty much 1 second longer.

What’s weird is that some attributes that change over the lifetime start from 0s (in my case the strength of the beam noise) but others start delayed after 1s (in my case the color).

What am I missing here?
