Zubinsum, pinotfan and seamar_116 all make their usual excellent points, and I'm a little embarrassed that they noted so many glaring omissions in my original post. It's a little hard to calculate the weighted impact of each of the SIM categories on HOFMC, much less explain it. The HOFMC is prorated across what I believe the SIM software developers call the "universe of SIM investment opportunities." Sorry, no acronym for that, although there should be.
And I believe pinotfan is right. The hierarchy runs HBD, Progressives, Themes (from longest duration to most recent), Champs Leagues and OL's. I completely forgot about the five-year bonus. My bad.
The impact of the hierarchy on owners with a positive HOFMC (over 1.00) is pretty straightforward. The relative weightings are something like HBD = 1.2%, Progressives equal 1.0%, Themes are a sliding scale of 0.4% to 1.4% (meaning that an acclaimed, longstanding theme league can actually contribute more than HBD or Progressives), Champs = 0.5% and OL is some complicated sliding scale of 0 to 0.3% that I've never really understood.
The negative impact on owners with an HOFMC under 1.00 is a little harder to explain but, in a nutshell, yes, you get penalized for relative inexperience in OL's, penalized again for lack of participation in Champs, yet again for lack of participation in Themes and so on through the Progressives and HBD hierarchy. SIM doesn't know the meaning of double jeopardy. The moral of the story is invest early and often and right across the board.
But before newbies get too discouraged, it is important to remember Zubinsum's point. The impact of the HOFMC is limited primarily to RC and its negative corollary, ERC, and its impact on most SIM metrics ranges from minimal to negligible. HOFMC gives veteran owners a nice little tailwind, but you can easily manage your way around it with sound team construction and savvy roster management. Newbie owners win WS all the time, and they usually beat owners with higher HOFMC's rather handily in the process.
Carp all you want, skunk, but last time I checked, your HOFMC was 1.0441. I don't think the existence of the HOFMC diminishes any of your 45 championships (well, maybe one or two).
