I don't do the Youtube "optimal" opener nor the rotation but overall I can put out about 4400-4500 (20-25 sec left) on every attempt at OV4S no pots/food at i339 head to toe Lost Allagan plus weapon. Not the best by any stretch but whatever.

That being said, i don't ever Flamethrower for the purpose of overheating into Wildfire. Rarely. Buffs throw off my CD alignments at times where I may have to.

Where I end up is right at 95 heat as Ricochet, RF, WF and Reload come off CD with no ammo in the clip. You can fill in the rest.

Again, its not optimal but it's a stress free 4400+ DPS rotation. And all I really do is open up with Hotshot-Barrel Stabilizer into the a GR-QR-1-2-1-RF-WF-3-Reload and so on. After building up my first 95 heat, I Cooldown, build it up again, by the time i hit 95 again, QR, RF, and WF are off CD. All my WFs thereafter lines up as such when all i do is quick reload as it comes off CD.
