Not everyone would agree on every good/bad, of course. Dummies 4141 and 22Re are fine with it; and the leader, mostly unscathed, has his biggest lead so far.

Fwiw, I appear to be tied for 2nd highest / best on r2.

Does 4th out of 6 somehow feel better than 6 out of 19?

4 out of 6 individuals who directly entered here doesn't sound like that much, except that 3 are top 6.

7 out of 23 total tracked is not bad, though I am often higher. Recent gains are encouraging and notable to me. Making use of the tracking data.

Lots of time left.

A link to the full projection table at least once (if convenient) would provide easier awareness of why / where leads and deficits are for the leaders and beyond.

Yes it is workable readable, thanks.



Compared to Pelton, I have a huge advantage currently on Hornets, moderate on Cavs. And Griz, Spurs and Wizards. He has huge advantage on Pacers and moderate on Heat. Nuggets, Raptors, Warriors, Jazz and currently Clippers, though that one is changing.

I'm in 4th place now and 0.03 behind second overall by average error. I feel good about possibility of getting to 2nd.

Fwiw, Pelton's entry was not a self entry in the contest but rather a pulled in by other, outside reference. So was DARKO. Dtka is the current leader of the official contest, by average error.

By R2, I am tied for 3rd and Pelton is tied for 6th.

1 team over 70% win rate and 7 more over 60%. Same as conclusion of last season except the top 1 is 7 percentage points lower (or 10% lower). I'd expect some increase in distribution spread.

I had 9 over 60% and none over 70%. Pelton, just 2 over 60%.

6 with 28 wins or less last season. 1 projected 6 to do that this season. Pelton just 3.

Long way from the final results.

Last season at this date there were fewer fairly strong records but more of the higher ones. Fewer poor records. Both expanded in frequency by the end of the season. If that happens, tightly regressed prediction sets will probably see increasing errors relative to less regressed ones. If the best don't get much better (and the worst worse) that could mitigate the impact of expected quantity of strong & weak teams.

Too early to say for sure but I am expecting these trends will generally help me comparatively.

I am now the leader in the APBRmetrics contest by average error, 2nd overall. Pelton's lead over me falls by .19 in last 2 days to .75.

(I was 2nd, now currently 1st in a different, outside contest on Western Conference record rank with 55 contestants.)

Pacers 5W-8L most recently with a pretty rough schedule in next 10 days.

Wizards continue to crash. I am still bullish on the Griz. BRef currently project 51.7 to my 52 and Pelton's 47. 2 straight wins for Raptors help.
