I was viewing statistics on this site, in comparison to runetracker.org (whose xp data I found to be questionable).

Then I note that the current #1 xp gain here, is Basey, who it says has gone from 16m xp to 2.349 Billion xp in one day.

On the accounts page, it also states that he has gained "most xp gained in a day/week" in every skill, on the the exact same day in every skill (July 25). How is this possible by any legitimate means?

"Most xp gained in one day - Constitution : 200,000,001" -- This is impossible since you start the game with level 10 HP, and thus already have like 3,840 xp or so in it from start.

I personally know Hotboy 2814 in-game (your #3 daily xp record holder) and he even says he didn't gain 2.6 billion xp in one day.

You need to take this site down if it isn't even going to record data correctly. There is no legitimate way to gain over 2 billion xp in 24 hours, even with playing nonstop, using effigies, bonus xp, double xp, soul wars zeal, void knight commendations, or any other in-game means.

Hello Mr. melachromatic, this is a glitch caused by a name change. In Runescape players can change their name, assume you had a level 15 account with a few stats around level 1-15 and you quit playing. After a few years that name would become available. If the name is a popular name or the player who had the level 15 account wanted to switch the name to his "main" account he could do so and on this site it would have the old stats for the level 15 and when the "main" account takes that name it would update the stats for that same name. Therefore all stats gained in-between when the first account was made and the "main" account received the name is recorded. I hope this makes since.
