Guild Wars 2

I noticed today several times this happening. Farming events, when I complete the event at the top it says I earned x amount of exp, and the karma reward was 187, but the pop up on the side says 202.
So I kept track and noticed the amount added overall is what is showing at top right, what I am confused about is the popup on the side being different.
Anyone know what/why is going on?

I’m guessing it might be an account wide Karma bonus you’ve gotten from your Achievement points Chests rewards.

Either that or Severwide WvsWvsW bonus – but I’m leaning more towards it being the Achievement points thing.

It’s your account-wide Karma gain buff.

The side popup is probably the karma acquired after boosting effect is applied.
If you have no identifiable karma boosts going on, then it could be the players in WvW fighting for their lives bringing you that boost. XD

Thank you all, Yes it is, I just did a quick one wrote everything down. Did the math, the increase was 8% which is what it was suppose to be. I miscalculated earlier which caused my confusion.
