I think the numbers vary a lot with the system architecture. My numbers are for Intel x64 - RSS is half yours while VM_total is double. Then again, I run only Seasons skin.
However, when I had the memory leak it was all due to data increment (showing up as RSS). The jump in total while RSS is stable could be loading more code, so I expect it should only happen once or twice then stabilise. We need to see longer term trends.
