For each class, what are efficient methods (like which weapons to use) to destroy the Tank Robot?

I asked this question so that I could know how to help quickly destroy the Tank Robot regardless of which class I'm playing as. I'm thinking of situations where I and my teammates have destroyed all the other robots, except the tank, which is coming close to deploying the bomb. In this case, every class should be helping to deal as much damage to it as possible.

Factors to consider:

- Sniper, Heavy, Pyro: Primary weapon or a melee weapon?

(Note that for most classes, only primary weapons are usually upgraded in MvM, while melee or secondary weapons are usually not upgraded.) - Other classes: Which weapons to use?
- Medic, Spy: Help destroy the tank (if so, which weapons), or another role?

Ok, I did some calculations for the sniper.

First, let's consider rifles. There is always the basic version, and the fully upgraded version. We are talking about killing the tank, so upgraded means full damage, faster recharge and faster reload, as well as maximum ammo capacity. Since the damage is subject to some randomness, I averaged the lower and upper bounds each to get my values. I also assume perfect reflexes for firing as soon as the charge reaches 100%, and the auto-rezoom feature enabled.

Sniper rifle:

33dps (down to 24 with 15s to find new ammo)107dps (down to 85)Huntsman:

41dps (down to 29)Sydney Sleeper:

33dps (down to 24)107dps (down to 85)Bazaar Bargain:

33dps (down to 24)107dps (down to 85)Machina:

33dps (down to 24)107dps (down to 85)148dps (down to 134)Hitman's Heatmaker:

Conclusion: Whatever you do, use the Machina, it has the highest damage in all catgories. (40 is close enough to 41 - don't say anything!)

Now to consider melee weapons. I also assume the basic weapon as well as the fully upgraded weapon. Upgrades are damage +100% and hit speed +60%.

Kukri:

Tribalman's Shiv:

Bushwacka:

Shahanshah:

Now, while this far the Kukri would be best, you might notice that we forgot about one circumstance. If you are below 50% health you deal much more damage with the Shahanshah:

With that in mind, a stunning 369 average damage per second, while you never have to reload, makes the machina with its 148 dps look like a toy.

EDIT:

(I deleted the previous calculations concerning other classes' melee weapons, because I clearly made mistakes. I also corrected the melee calculations for the sniper, which were wrong, too. I have no idea what I did a couple days ago. I redid the melee calculations WITH critical hit chance of 15%.)
