why every run in the 1.16+ category is 1.16.1? I really want to know if gives some advantage or something like that

Piglin bartering was nerfed in 1.16.2.

In .1, there's a 4.7% chance of receiving a pearl trade, and in that trade you can get between 4 and 8 pearls. In .2, this is nerfed to like 2.5% (not too sure on the number) and you can only get between 2 and 4 pearls per trade.

Because in 1.16.1 the pearl piglin trades, give more pearls than 1.16.2

So more pearls, more faster.

(sorry for the bad english i'm chilean AYAYA)

1.16.2 nerfed piglin bartering so speedrunners just use 1.16.1 to get better pearl rates

oh, thank you guys
