ok, i used the config i saw in other post ((((( E.g. High Damage setting: with 40% {Bonus} (highest possible BonusTierDamage=7):
[JoanPhoton]
BaseDamage=600.0
DamageMultiplier=3.0
BonusTierDamage=7
FireInterval=4.0

With above setting, versus a Giga with 1 Million Max Hp:
1 Stack: Result = 600 + (0.4 x 1,000,000) = 400,600 Dmg per 4 sec. Or 100,150 dps.
2 Stack: Result = 600 x (3.0 x 2) + (0.45 x 1,000,000) = 453,600 Dmg per 4 sec. Or 113,400 dps.
3 Stack: Result = 600 x (3.0 x 3) + (0.50 x 1,000,000) = 505,400 Dmg per 4 sec. Or 126,350 dps. )))))
