Can i assume you have 400 Critical attack on here?
[details=25% attributes]1,000 P.atk + skill damage (1000) * attribute 25% = 2500
On crit = (2000 * 1.5 + 400 ) * 1.25 = 4250
1,000 P.atk + skill damage (1500) * attribute 25% = 3125
On Crit = (2500 * 1.5 + 400 ) * 1.25 = 5187.5/5187
1,000 P.atk + skill damage (2000) * attribute 25% = 3750

Not sure if you want the total ratio or just the % damage increment.
Because if we factor in crit it’s a different story. a Non crit in this case is linear. So no matter how much you compare on non crit it’s flat bonus
Like for example 2000 Pattack total with 25% attributes versus 2500 Pattack total with 25% the difference is 1.25 @_@. or basically 25%
