Quick noob question.

Do you get less experience points in each dungeon after the first time you do it?

I did tempest island for the first time two nights ago and went from about 1/4 into 44 to almost 46. Did a few random quests to hit 46 then last night I did two dungeons (tempest island and another one) and started out at halfway through 46 and couldn't even hit 47 after two dungeons. The second night was done at veteran 1 rank so not sure if that makes a difference on xp earned.

Not complaining at all, was just curious as to why there was such a drop in xp.

Thanks in advance for any insight.
