I don't think Steam would be totally reliable for playtime if it was applied to refunds. A few months ago I used ccleaner and screwed up my graphics driver. I was trying to play a game that I had just bought, but after my mishap with ccleaner it never worked for me, though I did add a couple hours to my total playtime. I fixed my computer by reinstalling windows, but if the problem was with the game, my play time counter alone would not accurately reflect the fact that the game was unplayable.
