Hi,
According to the logs, the display name "Markelliss" was not on the RuneScape highscores on February 20-21, so no stats were recorded for those days (and thus the stat gains for February 22 when your account resumed being on the RuneScape highscores did not count as it's impossible to determine what amount of xp was gained for each day during the time your account was off the highscores).
I see that you changed your display name on RuneScape from "Markelliss" to "Okinawa Jp" on February 20, but did not update this change on RuneTrack until a day or two later (or someone else updated it for you via the
Name Change Contribution page). This is what caused the disruption in stat tracking for your user profile. The day or two between when you changed your name and your RuneTrack profile was updated could not be tracked, as Jagex removes the link to the highscores immediately for accounts which change their display name.
In the future, remember to update your RuneTrack account immediately if you ever change your RuneScape display name to prevent any interruption in stat tracking. Unfortunately Jagex makes it difficult for fansites to detect and track these name changes, so the system relies on the players helping out with keeping the name changes up to date.
