Comparing DPS of Jumbo and Double Barrel Boomstick [S02.H6]

Build: (2)-(2/1)-(3)-(3).
Jumbo can win only under following conditions:
1. You click like hell Double Trigger every time.
2. You greatly compensate Double Trigger recoil that really hurts your damage.
3. There is no lucky breakpoint for Barrel on your current Hazard Level.
Because of that, Double Barrel has better DPS in your games more likely.

Ideal DpS (based on Weapon Damage and delay+reload between shots):
Double Barrel: ~198.3.
Jumbo: 200.5.
Stuffed Shells: 190.8.

Taking my manually clicked delay (I tried):
Double Barrel: 189.7-196.
Jumbo: 195-198.5.
Stuffed Shells: 184.3-190.8.

Losses on my Crassus test due to 60% Light Armor blocking my damage:
Double Barrel: max 12.2% dmg lost, avg 3.6% dmg lost.
Jumbo: max 30% dmg lost, avg 10,7% dmg lost.
