see above

That's how the ratings work.

Re: John t whelan ranking simulator

Just thought of another issue with the new RPI calculation. In the conference playoffs, couldn't there be a clear advantage for a higher ranked team to play on the road? The difference between a .8 multiplier and a 1.2 multiplier could easily be the difference for a team on the bubble. Shouldn't a higher ranked team have the option to opt to play a two-out-of-three playoff series on the road? If not, why not? Note that the home advantage (as traditionally estimated) is nowhere near the RPI differential, so, other than the fact that you lose the gate receipts, shouldn't it be the normal call if you're on the bubble?

is the denominator always the same?

If so, in short, yes, but that perverse incentive will be there for any team. What isn't sure is it worth losing to get into such a situation. That'd be a risky move. I don't think I'd take that risk... could just go 2-2 or worse than 2-1.

The denominator is dependent upon who wins the game. If the home team, it's 0.8 for both. If the away team, it's 1.2 for both. Of course for the non-school-rink situations, because it is always the league that hosts and not a specific school, those are worth 1.0.

So that definately mutes any strategic advantage. Not that weird things can't happen. Personally, I'd love to lose one and win two all year long as that'll probably get you in

Re: John t whelan ranking simulator

My point is that a team on the bubble may need to take a risk. It could be that 2-0 in your rink just isn't worth very much and 2-0 in the other guy's rink is worth enough to make the risk worth it. Take the obvious example where a win over someone in your rink would be dropped from RPI while a win in their rink would augment RPI. In that case, playing at home is all downside. (And in the ECAC for example, the first round is 5 vs. 12. A really bad #12 team would be exactly the team you want to play in their rink, and the #5 ECAC team is probably real close to the bubble.)

I don't think math is going to be your friend.

Tell you what, take a home win prob of .55 under the two scenarios...

This is a short sim but I'm headed to a birthday party in dupont. Seeing as the denominator scales with the numerator I'd find it hard to believe there would be an advantage.

If you disagree w .55, sure, modify. But I'm almost sure of myself that your life is better playing for the first win and the home series than plopping in a loss

Just surface, N-H-H 3 wins

+2.6/+2.6

Vs n a a 2-1

+2.4/+3.4...

Don't even get back the same count of adjusted wins. There can be a lot of odd interplay when you add the bonuses... But first principles... Smaller numerator, larger denominator implies a smaller value... And this your base should you add tweaks... And you are likely to lose away... Christ that was a quick trip.

Re: John t whelan ranking simulator

It clearly doesn't make sense to lose a game in order to play on the road. I was proposing that the team with the home ice advantage have the option to play on the road. That could clearly be in their advantage. Take a case of 5-12 matchup. That could easily be 65 percent at home and 60 percent on the road. Now the numbers work out.

Has anyone figured out yet why FlagDUDE's numbers don't match JimDahl or RHamilton?

Right but its an unavailable choice... Of course this is ultimately the question of if teams should be road warriors.

Not yet; I am going to make a debug build of the application that gives every calculation step by step and see where things are amiss. I know one difference RHamilton and I discussed involved how we are removing the games that negatively affect RatingsPI.
