Since you 'had to make a decision' then the decision becomes non-mathematical in the strictest sense. But a bigger K creating a bigger spread changes the odds and therefore the effect of the result of the next game, does it not? If I am missing the math, I would love to see, with rigor, how it makes no difference. And, I say that as a math geek, with a slight inclination in the back of my mind how that math would come out. If this is subjective, then the 'guess' as the correct value of OT/SO wins and losses is also, as well as the value of K. And, as described below, there are mathematical ways to determine the value of home ice as a league average. It is a cold mathematical process, but it can be skewed by the following. Let's say there are 32 teams, instead of 31, so we don't offend anyone, and let's say that the last team in (International Falls, MN) is globally acknowledged to be the worst team in the league. Now, let them win their first 3 games, 1 in OT, because their goalie is particularly hot. Everyone knows that this is a mirage. It won't last. But, their 4th opponent, who beats them, gets major points for this win. And, after they lose 9 more games out of 10, the next opponent, who beats them, gets minimal points. That seems mathematically correct, but not completely sensical to me. Even though I know that all teams have injuries, and so one team's power level is not the same all year long, so teams do have scheduling advantages of playing some one "at the right time", I feel this system unduly rewards teams with scheduling luck to play weak teams with fast starts. That could well be your preference, and I wouldn't argue with your preference, but it is really a preference. This article (pardon the few typos. I wrote it as a post, and the mods moved it. Had I known it would be an article, I would have proof-read it better) gives the basics. Should you be interested in more mathematical rigor, or how I arranged the spread-sheet to accomplish this, please PM me. And, it should be noticed that those rankings recalculate from scratch after every game.
