You need to fine tune your index by assigning a pulled-from-random but defensible multiplier for Away games.
If you want to help with the Home Game Handicapping Project, please answer the following questions. Just give a quick, best answer. Don't spend time researching or thinking too deeply. Thanks.

C. Portland
D. Galaxy
2. Playing the LA Galaxy at home is roughly as difficult as playing which team on the road:
A. Vancouver
B. Montreal
C. Columbus
D. New England
3. Playing San Jose on the road is roughly as difficult as playing which team at home:
A. Seattle
B. Orlando
C. LA Galaxy
D. Portland
4. Playing Columbus on the road is roughly as difficult as playing which team at home:
A. Toronto
B. Houston
C. LAFC
D. Sporting KC
Not sure that’s the right way to approach it. Not saying this is, and any math/statistics forum members should chime in, but just approach it purely as a math multiplier.
Any results at home are straight-up results with a multiplier if (x1) - it could be argued that a tie at home should be penalized, but I’m trying to simplify it for this round.
Points earned away should be worth more, but not so much that it skews everything, so try plugging in (x1.25), so a tie is effectively worth 1.25 pts and a win is worth 3.75 pts. This will give value to securing results away and differentiated teams that have played many away games from those that have played a lot at home. And maybe 1.25 is too high in the whole scheme of things.
Then for position in the single table, use a multiplier of (x1.0) for the SS table #1 and (x0.99) for #2, (x0.98) for #3, or some variation of that.
This way, it’s not so much of an eye test and more of a real algorithm.
First, when I told Gator he needs to do this it was in jest, unless he wants to. Not that I'm worried he feels compelled by my suggestion, but I just want that out there.Is it relatively easy to pull home vs away PPG for 2017 and average across teams?
Second, I think Ulrich and Mr. Jee are on the right track. It was easy for me to pull the H/A split for interconference games last year because I have that all tracked. Everybody went a combined 1.91 PPG at Home and only 0.83 Away. I doubt this is a good proxy for the entire season because interconference play means longer travel, but that is 2.31 ratio. If it were the right ratio that would mean dividing the value of playing any team away by that 2.31. But I think Ulrich is right and the actual ratio, whatever it is, should be collapsed somewhat or the skew would get too extreme.
