No the XP value change was only applied to certain units. As I said XP values are mess.
We are talking about different things.
What you usually refer is to xp requirements for veterancy. I'm talking about the unit xp value which is tied to vet level.
Vet ranks are expressed in numerical values with specific increments. If a unit needs 100xp to vet1, it will be listed with experience_value: 100f and then double that amount for vet2 and so on.
But what that unit receives on each vet level is a modifier which increases the value of the unit, which with outdated extracted attributes shows as plain x1.16 or x1.20 per vet level. In some OKW units only appearing in 4 cases and in others 5.
