Patch 4.05 Machinist Rotation: To Overheat or Not to Overheat? Here are my findings.

[Elnidfse]

You're missing a GCD. That hotshot is also weird since in an optimal rotation that'd probably be getting applied right when it falls off. Assuming it's on before wildfire anyways. Which should be before you apply reload.

Now that I think on it your reload is also delayed by 2.5 seconds. On the topic of Gauss round you'd be able to weave it in front of the very first 1 and have it again before Wildfire goes off.

Getting to the nitty gritty;

There's also a potency problem on the non overheated combo.
GR + split should be 415 but you have it listed at 395. Also your 2 on the -0.5 second is measured at 400 when it's 230 at most
Auto attacks also aren't accounted for which will range in that time from 3 to 4. My weapon gives me 86 potency a piece.
You can do 2 Cooldowns in a non OH wildfire.

Damage on the right is lower than it should be and damage on the left is higher than it should be. Run another pass through your math.
