New, Better Formula For Calculating The GDF

The formula for calculating the Goaltending Dominance Factor has been amended to better reflect actual goaltending performance. The original formula was based on save percentage over a number of games played (a minimum full-value mark of 13 games played over ten sessions), which has become an outdated concept in an age when some goalie are facing 60-plus shots in one game while others face 60 shots in an entire session. To make the formula more accurate, the minimum full value has been changed to save percentage with at least 100 shots faced over the last ten sessions. As all major goalie records are based on shots faced rather than games played, this change to the GDF brings it in-line with the way other goalie records are calculated. This also follows 2005's recalibration of the Scoring Dominance Factor (SDF) to reflect sessions played and quality of competition faced rather than purely points-per-game.

Why did I change it? Simply put, having a ranking where a mediocre goaltender who faces half the shots shots can be ranked ahead of the person having the greatest goaltending season ever is silly. Here's an example of the change; I think you'll agree that it's much better:
