  ×25% gives you 1/4 the original value, whereas +100% is double the original value, let’s say 8/4 to keep it consistent. ×125% (in case a 1 is missing) is still only 5/4 the original value.

  Is there a typo in your comment?

    In video games they commonly use that to mean they are multiplying by 25. We know it’s not correct in stats.

      Biggest lie in gaming was how the formula for Armor Piercing rounds in Fallout 1 and 2 was bad, so instead of being stronger than regular rounds, they were weaker.

      Games use x25% or x25? Technically the first divides the score by 4.

        We are aware of what it actually does mathematically. Please re-read what I wrote.

    I feel they might’ve left something out. If you’re at base value still an additive 100% increase (1+1=2) is better than a multiplicative 25% (1×1.25=1.25) increase but in games where bonuses stack another additive 100% increase would raise the effective value by 50% instead (1+1+1=3) whereas another multiplicative 25% would still raise the total by that much (1×1.25×1.25=1.56) so if you’re stacking a lot of bonuses, eventually the multplicative ones are more effective. As for how many steps it would take to be equal in our example… 1+1×X=1×1.25^X I’m not gonna do this in my bed on my phone but that equation should already tell you that the right side grows faster when X -> infinity

      It’ll become greater after 12 applications:

      1. For 11 times 1.25¹¹ ≈ 11.64 < 12 = 1+ 1×11
      2. For 12 times 1.25¹² ≈ 14.55 > 13 = 1 + 1×12

      There’s no need for a precise solution since it’s integers anyway.
