Yeah, there's always the issue of games you miss, and those will lead to (subtle) differences. But it's still quite interesting to have some sort of overview, to have something that you can look back on, rather than going by your own selective memory.
For instance, I'd never come up with Gio (and possibly Vidal, like you mentioned), if someone were to ask me who have been the best performers so far. Because that's not how I recall the season so far at this moment. But adding up all individual games/performances, that's what comes up...
