WEI Score Different from Inital Score

[The Napster]

Hi, I just got a new dell laptop with a touch screen. I just received it and I updated from windows 8 to windows 8.1 and ran a Windows Experience Index Formal Test which scored .3 lower than the initial formal assessment. I was wondering if anyone knows what causes this. I've looked through the logs and the difference seems to be in the gaming graphics section. I will post the main sections of the tests below.
