Two questions:

1) I am wondering what the standard qos setting exactly means, does it prioritize one of the applications/activities over others (gaming, streaming, chatting, surfing, downloading over others?).  In other words, if I go to custom and put everything on the middle level, does that do the same as traditional? 

Or is traditional its own unique configuration/balance?

2) Also a follow-up, if on custom i put everything on maximum, is that the same thing as putting everything in middle in the sense that all prioritzed the same extent, or does all application being on "Normal" versus "Maximum scale" make a difference in theory and practice?
