This is unbelievable. You guys are making Amazon pointless. Amazon has now been right every single time, including April, because of 'a', 'b' and 'c'. Why is Amazon known to have been wrong once? You people are overcomplicating what was a very simple concept.

If the PS4 is ahead of the XB1 in the monthlies and the XB1 wins then Amazon will have been wrong for the second time. If the PS4 is ahead of the XB1 in the monthlies and the PS4 wins then Amazon will have been right yet again. This is how it's always been judged and I haven't got a clue why some people now want to complicate this simple fact.

Whichever console leads the Amazon chart is seen as the winner of the month.

You may be seeing it as simply as that, but I've always looked at Amazons predictive value in more depth. So the top selling sku has a high predictive value, but there are circumstances where it falters, and then you have to go into a bit more depth to see what Amazon is really telling you. This month I don;t think we can say what Amazon is telling us at least until we get the final monthly chart. You say Amazon has been wrong once, I say Amazon was right in that month. We're both right it just depends on what you chose to measure.
