Chart Run Predictions Game

Introduction
Each week from Sunday at 7:00PM (when the UK Singles Chart Top 100 is published) until Wednesday at 6:00PM (before the Chart Update) you must predict, for new (to top 100 or 200) and re-entries (to top 100 or 200) in the top 40 the chart runs for them. It is like Chart Predictions, but you have to predict individual singles, and it is not just for the next chart week, but for its entire performance until it drops out. The reason you may only predict between Sunday evening until Wednesday evening is because the new and re-entries in the Chart Update may differ to the end result on the top 100 chart on Sunday.

Example
You Make Me by Avicii is currently new at 4 on the Chart Update. You must first wait to see if it will still be 4 by Sunday before making any predictions. Once the position is confirmed, you may predict the position in the chart it will be the following week, and consecutive weeks after that, until you predict it will drop out of the top 100. You have until 6:00PM on Wednesday to predict the song's entire top 100 chart run until it leaves the top 100. Remember you cannot change any of your predictions for that single after Wednesday.

Each week you must compare the position you predicted the song to be at against the song's actual position. The difference in positions is the amount of points taken away from your 1000 points. If you predict the song to drop out too early, each week the song stays in the chart after the predicted dropout week is minus 20 off your score. If the song you predict drops out earlier than predicted, each extra week you predicted in the chart is also minus 20. You must do the whole chart run predictions for that single BEFORE the Chart Update, and you have until then to alter your predictions as well.

Remember, the debut or re-entry position (the first week) is NEVER predicted.
