>a price of a good cannot go down by more than 100%
say you're looking at data that begins with the price of eggs in like 1950, and they're $0.01 per egg
let's say one egg is $1 today (they're not, bear with me)
that's a 9990% increase in price

now, you're probably seeing where i'm going with this.
however, go fuck yourself, because making it to the level of a 8990% increase instead of a 9990% increase is in some sense (though admittedly not a conventional one) a deduction of 1000% in this scenario (though not a 1000% deduction)
>nooooo percentage decreases are capped at 100%!
small brained, no creative spark, no imago dei, sad.
