Score weighting

gistfile1.cs

DateTimeOffset startingPoint = new DateTimeOffset(2008, 4, 1, 0, 0, 0, TimeSpan.Zero);

            // this calculates a score to be used for how hot an Audio is, a boost is given to Downloads over plays, same for likes and favourites
            // with a favourite the most valuable, a single favourite stat is worth 20 points where as a play is just 1 point
            var playScore = Math.Max(TotalPlays / 1.5, 1);
            var downloadScore = Math.Max(TotalDownloads * 2, 1);
            var likesScore = Math.Max(TotalLikes * 4, 1);
            var favScore = Math.Max(TotalFavourites * 5, 1);

            var score = Math.Log10(playScore + downloadScore + likesScore + likesScore + favScore);

            double seconds = (this.DateAdded - startingPoint).TotalSeconds;

            // 200,000 seconds = 55.55 hours - the higher this value the more weight is given to older audio documents
            // currently this will give good weight to audios with high stats that are around 10 days old
            // may nead to be tweaked to get better results
            var result = Math.Pow(Math.Round(score + (seconds / 2000000), 7), 0.25);
