If prediction league is what it sounds like than I would pick that for sure.
Can someone describe to me how prediction league works?
These were the rules:
So you want to be a contender? Do you think you can out-estimate the analysts? Show off your predicting prowess in the VG Chartz Prediction League.
How to Play
Each week we will create prediction rounds for Japan, America and Others. In each round you must submit your predictions for the ten software and five hardware sales using our entry form. VG Chartz will provide a list of software and hardware for players to predict sales of (generally expected to be the top performers for that week). To qualify for a given contest, your entry must be received before the closing date. Occasionally, VG Chartz will post some one-off prediction rounds covering sales over a quarter or a year. These rounds can be entered in exactly the same way as the weekly rounds.
Betting on your predictions
Each prediction you make per round has a minimum bet that you must place of vg$5. This means that across the 15 prediction fields in each round the mimimum total bet is vg$75 (15 x 5). For predictions you feel more confident about you can bet more against, for predictions you are less confident about you should bet the mimimum amount. Your total bet amount over the 15 predictions in a round cannot exceed your current wealth - i.e it cannot make you bankrupt to place the bet. Think wisely about your predictions - use the charting and comparison tools provided by the website to look over historical data and place your money wisely on the predictions you think will pay out the most!
Winnings are determined by your prediction accuracy. Prediction accuracy for a each prediction is calculated as the difference between your prediction and actual figure / actual figure. The prediction accuracy for each prediction is divided by the average accuracy across all users for that prediction and then this ratio is multiplied by your bet on that prediction. This is totalled up over the 15 predictions. An example is the best way to illustrate.
You predict a game will sell 175,000 copies for the week and the game actually sells 200,000. So, we take the difference between your prediction and the actual sales and divide it by the actual sales 25,000 / 200,000. The result, 0.125, represents the percentage your prediction was off from the actual (12.5% off). Subtracting this number from 1 (one represents being wholly accurate) tells us how close or accurate your prediction is to the actual: 1 - 0.125 = 0.875 or 87.5% accurate. Note that if your prediction is off by more than the actual amount (i.e., off by more than 100%), your accuracy will be 0% representing the fact that you were simply not accurate in your prediction (e.g., you predict 100,000 and the actual is 30,000). Your accuracy is then divided by the average accuracy for that prediction, in this case say 50% (100,000 as the average prediction) to give (87.5/50) then multiplied by your original bet. So if you bet vg$10 on this prediction, you would win 10 x (87.5/50) = vg$17.50 (a net profit of vg$7.50 against the original bet). This is repeated across all your bets and totalled up.
VG Chartz will post the results of each round, one week after the actual data for that period has been posted on the site (to give time for any adjustments to the actual data). Once your bets have been cashed in, changes will not be made if adjustments are made to the actual data on the site later on.
VG Chartz will be the sole determinant of player accuracy and scores. We reserve the right to disqualify anyone from the leauge for any reason. Questions about the contest should be directed to email@example.com.
