Experience Loss at Death

I saw some posts around the April time frame regarding exp loss on death being broken &/or complained about, but after the last major update &/or hot fixes, I’m just curious what the xp loss is supposed to be. ~50% of current seems pretty hefty imho. I’m mainly asking as I’ve read from 10-25%, but I’m seeing significantly higher than 25%.
Thanks for any information.

It used to be 5% per enchantment and those did stack from multiples sources. Maybe even 10% cannot remenber anymore.
