Is there a leaderboard or anything up for killing specific things as quickly as possible?

I'm currently farming Adamantoise's and Adamantortoise's for ingots and to help pass the time I'm trying to see how quickly I can get them down. So far my PB's are

Adamantoise - 1:32 Adamantortoise - 1:33 Adamantortoise + Gorgonopsid - 1:42

I don't have fully upgraded weapons/accessories yet and this is just normal fighting and not using the Death method. Also this is on Xbox version.

I'm curious as to whether there is a WR for turtle kill time out there as a target to aim for.

Thanks!
