Halo 5 Warzone Powerups Question

My only question with the warzone powerups (camo, os, damage, and speed), is the difference in duration between each tier. Does anyone know exactly or approx?

The higher the boost tier, the longer the duration. That’s the only difference.

Yeah I get that. I was asking how long the difference is. Is tier 2 double what tier 1 is? Is Tier 3 four times as long as tier 1?
