  In case it's missing, I think parent's tongue is firmly in their cheek - point is things like '4500%' are often manipulatively rendered that way to sound massive, vs. '45x' for example, which means the same, is just as massive, but perhaps doesn't sound as crazy?

  Percentage are broken in many cases because they are ambiguous, and often difficult to compose. +50% then -50% is not identity but ratio 3/4. A plain explicit ratio is sometimes better. Ratio in decibel, or "doubling number" can sometimes be valuable alternative, could be used more often. +1 doubling -1 doubling is identity. Same for decibels.
