5102Re: [hockeydisk] update on new disk
- Sep 27, 2013This means to run the disk as is, with 48 games played, but calculate usage away from the disk.
So, use the disk as is, but, for example, for Vinnie Lecavalier, who played 39 games, handle his usage (GP limits) as 39x1.7, or 66 GP. Do usage limits offline, not on the disk in the GP field.

What I would recommend is to scale usage offline, using the 1.7x GP guideline, but don't change it on the disk

I'm debating whether to issue a "pro-rated" disk or not. Not all ratings scale linearly in the game, so a simple 1.7x won't solve all issues. Definitely need to take all relevant stats up the 1.7x factor, just moving GP up will give crazy results. I'd like to test a 1.7x translation to ensure no wild behavior, but that would take time, and I know people want to get on with their seasons. What I would recommend is to scale usage offline, using the 1.7x GP guideline, but don't change it on the disk. Changing it on the disk will effect results, as many are proportional to "per game" calculations.

Thanks for the update Dave...A question many of us are pondering is how to best use the new disk, which is based on the 48 NHL season, for a full 82 game apba schedule.Some ideas I've heard include multiplying all of the counting stats and GP by 1.7 to bring it up to a full 82 game season. Another idea is to just multiply the GP stat, and leave everything else alone.
Would you please comment in detail on what your best recommendation is for a league wanting to use this new disk for a full 82 game schedule?Your efforts are very appreciated. Thank you!

Currently at the very end of the testing period. Got to a conversion
point that was acceptable, now just cleaning up some loose ends (like
goalie assists). Hope to migrate to combined disk over the next 4-5
days, and get the draft disk out to the team for error checking. If all
goes well. Hope to release final disk by Oct 8, barring any major error
I really wanted to get this year's disk out earlier than in the past,
and with Ken's great new rating vote system, I had the rating info much
earlier than past years. However, you can blame Bettman and the lockout,
as the short season made the testing difficult. The variabilities on the
numbers are much higher than past seasons, so getting convergence on the
disk has been a headache. I can't say that I'm thrilled with the disk
this year, it is reasonable, but not spectacular, mainly because the
variability numbers on a short season are just too large. Extra testing
was needed just to ensure that changes weren't random variations of a
small sample size (read: short season) or real effects. I did the best I
could, and it's a good disk (but probably not a great disk). Sorry.
Blame Bettman. We won't have this problem again now for a few years, so
we'll let it go and move on. I'll you all know how progress is going and
give you a solid fix on the release date in a few days when I finish the
migration. Hang tight, we're getting close.
