Lowest Cost For Farmer Villager Trades

Hello, I just returned to my world that I created in 1.19 a few years back. I found out that in 1.20 they changed a feature where the cost of villager trades no longer goes down if you cure a zombie villager multiple times. So does anyone know the lowest cost for trading crops to emeralds for Farmer villagers now because I have a few from 1.19 that trade 1 crop for 1 emerald but now they won't go much lower than 15 crops for an emerald.
