Secret: Sales Prediction?

[truehappiness]

I wonder if the progression will be like Memorial address' or MY STORY's..

Memorial address:
524,028 (1st week sales)
306,521 (2nd week sales)
63,471 (3rd week sales)
36,190 (4rth weeks sales)
24,121 (5th week sales)
17,520 (6th week sales)
11,479 (7th week sales)
9,993 (8th week sales)
total so far: 993,323 <-- [in the 10th week, it hit million]

MY STORY:
MY STORY- Week-1 Position: 1 Sales: 574,321
Week-2 Position: 3 Sales: 194,556
Week-3 Position: 3 Sales: 190,471
Week-4 Position: 4 Sales: 38,792

Total: 998140
[obviously it got to a million in within about 5 weeks ]

(Someone smart wouldn't 'joke' that it would sell one copy in the first week, when obviously many are preordering every single day D: )
