The whole bias discussion makes no sense because Amazon only gives rankings, not quantities.

On COMG we can tell if there is a bias because they dont only tell us the rankings but also the exact number of pre-orders so we can compare that to actual sales.

On Amazon we have no idea how close each ranking is in terms of units sold. For example

January Amazon rankings
NSW-13, 17
PS4-34, 53, 63
XBO-52, 68, 85

13 & 17 could be 8000 & 7000 units for a total of 15,000

34, 53 & 63 could be 5500, 4500 & 2500 for a total of 12,500

52, 68 & 85 could be 4700, 2300 & 2000 for a total of 9000.

Now lets say NPD figures for January are

NSW-300k
PS4-250k
XBO-180k

That would make the Amazon % of NPD totals the same for each console which would result in no bias.

Thankyou! Its soo easy to understand but some people are just..........
