@koffie.
What do you mean?

I said earlier I am (almost) sure.... the final points will be added up week by week (so if week 1 you are 10% off on each platform you will "gain" 50 points, then the same for weeks 2-10) After which the total for 10 weeks will also be calculated, and the score multiplied by 5 and added to your total.

So for instance you may do quite poorly in the weekly rankings by being 20% over, then 20% under, then over etc... alternating each week and giving you 200 points, but your total amount is then very accurate, so you might only be 2% out overall, and only gain an additional 10 points to make 210 points overall.
Meanwhile someone else may be only 15% over for all 10 weeks, and thus get 150 points, but then be 15% over for the total, and gain a further 75 points to make 225

Here... I did:

I didn't see that as final confirmation but more as something you were still considering.

please don't compare it to total sales

I'm personally in favour. In the end the totals are more important than being right some specific week.

In general people should be more accurate for total sales than most of their weekly estimates. (ie apart from weeks 1-3 which everyone should do quite well on)

Haha well it is quite obvious that for total it'll always look better. Larger numbers obviously have a much wider margin of error. Meaning you can be at 9 million when the actual number is 10 million and that is equivalent to predicting a week of 450,000 and it actually being 500,000. So yea as long as no one had some completely outrageous predictions everyone should do generally decent on total sales.

Ok gang!

ready to get started tomorrow, remember I need at least one of you to post the weeks figures as soon as they come in. Should have no problem with people being online at the right time when there are 24 of us (and the number updates seem to be consistantly Thursday night now, which is useful)

I think I will normally be online Thursday nights myself, but feel free to try beat me faster the better.

What if some week's numbers are adjusted afterwards? What do we do with that?

^That's what the difference between "original" and "final" is on the tables on the first page.

The original VGC figures will be filled in as we go along, and we can get an idea as to how we are doing like that.

The final figures won't really be final because adjustments quite often back-date a long way... for instance the ones I used for last years I collected from the site in July, but when I posted the article they had changed again by a few 1000 units.
However if I wait until a couple of weeks after the Fiscal Year results are in (ie mid-late May 2010) then any major adjustments to the Christmas 2009 figures will be over, so it should be accurate enough.
