Hyper Experience inconsistency

[zeroneon]

Minecraft Version

1.20.1

Describe the Bug

I tested out bottles o' hyper enchanting in a creative world and it seems that they are extremely inconsistent.
I threw a stack on the ground, my levels slowly rose until suddenly, I gained a massive amount of levels, seemingly multiplying. With less than a stack of them I reached level 40000.
I tried to test it again and threw around a stack onto the ground and I didn't even reach level 40001 halfway.

Reproduction Steps

1. get bottles
2. throw bottles
3. profit
   ...

Expected Result

Much less experience gain

Other Mods

Maybe Clumps has to do with it, a mod that clumps xp orbs together but it didn't seem to affect anything
