Losing 2x PvP points?

Anyone else losing ~2x the PvP point compared to what the game says?

Was at ~800 and left, come back and it says I lost 160. But I’m at 480 not 640. Second time this has happened. Didn’t bother to add up the individual hits, but I’ll do that next time.

The notification window for defensive PvP battles only reports the last 5 battles I think. If you lost 300+ points, then you were probably hit many more times than that limit.
