I was in the mood to do some excel tables so here are a couple in case anybody is interested.
| System | NPD | VGC | %Difference | Range when accounting for margin of error of each source (.1) | Agreement of Sources |
| DS | 398,400 | 387,000 | -2.86 | 78,540 | TRUE |
| PSP | 84,000 | 54,000 | -35.71 | 13,800 | FALSE |
| 360 | 443,500 | 336,000 | -24.24 | 77,950 | FALSE |
| Wii | 253,900 | 240,000 | -5.47 | 49,390 | TRUE |
| PS3 | 214,500 | 176,000 | -17.95 | 39,050 | TRUE |
| System | VGC(%difference from NPD) | Wedbush(%difference from NPD) | EEDAR (% difference from NPD) |
| DS | -2.86 | 1.66 | 1.15 |
| PSP | -35.71 | 1.19 | -20.24 |
| 360 | -24.24 | -19.95 | -30.33 |
| Wii | -5.47 | 22.10 | 7.92 |
| PS3 | -17.95 | 7.23 | -6.29 |
| Absolute Value Average | 17.25 | 10.42 | 13.19 |
Well as much as we as like to make fun of Pachter's predictions, at least this month anyway he seems to have done a pretty good job lining up with NPD.
