Zombie Curing discount only drops the price by 1

I know this update tried to bring villager trade discounts closer to Java, instead of dropping everything to 1 per, however, with this update, it only drops the price by 1, i.e. from 26 potatoes, to 25, while on Java, its drops it from 26 to 20, while I personally prefer the pre-update discounts, I would rather then not only drop by 1.
