I am just letting all of you guys know that the xp from urns are incorrect in the calculator. They do not match up to the ones listed on the Skill Guide and I tried in Runescape and only got 1900 for a decorated urn which matches with the xp listed on the Skill Guide.

Reading instructions is highly beneficial, taken from the box the handly pops up right in front of ur eye lvl when u pick urns:

 

"Information

The XP value listed for an urn is equal to the amount of XP needed to fill it, plus the XP bonus awarded for teleporting the urn.

 

For example, you will need to catch 750 XP worth of fish to fill a cracked fishing urn, and teleporting it will award 150 XP, for a total of 900 XP."

 

The numbers are perfectly fine, as they list the correct total xp for filling AND teleporting an urn.

As Sy has stated, it's not just the xp for teleporting away. If you have any further questions, feel free to PM me.
