Gulper: independent debuff/buff count?

“This creature deals 50% more damage for each buff and debuff if has greater than its target.”

So, how does the damage work out in these cases

enemy 1
debuffs: 2
Buffs: 0

Player creature 1
debuffs: 0
buffs: 5

Would that be 250% extra damage or 150% extra damage?

debuffs: 7
buffs 0

player creature
buffs: 7
debuffs: 0

Would that be 0% extra damage or 350% extra damage?
