Technical question about experience gained from rezz

[Kiwix]

Just some facts for starters:

I am aware of that experience penalty from dieing is calculated as 10% of the previous level gained. Aka at lvl 54 I would lose 10% of the experience gained in the previous lvl 53/54.

Now to my question:

Lets say I de-level from lvl 53 to lvl 50. From lvl 50 I will start to do some sacking to lets say lvl 46.

At lvl 46 I will then rezz up my old corpses (from when I was lvl 53, 52 and 51).

Would the amound of experience gained from the rezzes be calculated from the experience gained at lvl 53, 52 and 51 or from the level I am when the rezz is made, aka lvl 45/46?

The difference is huge, so I'd love to know before I plan when and how to do my sacking.

I hope it makes sence and thanks in advance.
