Currently the "travel 200 blocks using ender pearls" quest uses the distance between your player and the pearl at the moment the pearl lands.

If you go to spawn, throw a pearl in the air, teleport home, then let the pearl land, the quest would consider you to have traveled over 50,000 blocks from your island to spawn.

The proposed improvement is to use the distance from where you threw the pearl to where it lands.

 

i think its actually kinda cool we can do this. you dont have to if you dont want to, but for other players, its a fun and easy way to complete and earn a quest point

 

I just jump straight up and throw the pearl straight down. Would still count as 200+ blocks if this was implemented.
