Let me bold that for you

You can't just take increase in burst damage and divide by number of turns in burst cycle and state "that's your overall increase in damage", because it's not. Assuming this burst every 6 turns and assuming burst are doing about third of your total damage, increase won't be 1% but about 2% (still not impressive, but value is already doubled).
My point was about some weird dividing. 1% increase per turn assumes 6x FB dmg in those 6 turns.
On another note, let me remind you that 3 small exceeds on 30 slvl equals to Asherah's 4 stacks of burst damage buff.
