Great work as usual. Many thanks.

Is it a simple matter to report on margins of victory in those same games? I can imagine how it might not be -- but if it is, I for one would be happy to see it.

Not sure I understand what you mean by this, Jay.

Could you clarify?

[Jay Edgar]

I didn't phrase it very well. Should have asked about "margin of victory in all NBA games in that time period."

Meant to ask this: without regard to the spread, what % of all games "land on 1" (the winning team's straight-up margin of victory is 1 point). What % of games "land on" 2, and 3, etc?

I'm routinely living in terror of a 1 point win by the team I chose to back at -2 rather than with the ML, etc. So it'd be nice to see a full MOV picture to get a sense of how many games that are in doubt in the last minute (say, MOV of 7 or less) actually land on 1 or land on 2.

Well to be fair, I didn't actually see your last post until 11:40 ...

[Jay Edgar]

Was there really an NBA game decided by 92 points in the last 15 years?

(I'm sure that if someone identifies it the rest of us will say, "Oh yeah, I remember that.")

Unless Detroit really beat Seattle by a score of <a href=http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/pastresults/1991-1992/team404316.html TARGET=_blank>92-0 on March 10^<u>th</u>, 1992</a>, then this was just bad data.

(The final score according to <a href=http://www.databasebasketball.com/teams/teamscores.htm?tm=SEA&yr=1991&lg=n TARGET=_blank>Database Basketball</a> was DET 92 SEA 98. I've modified the chart to reflect the correction.)

[zxcjason]

Ganchrow, where do you find the point spreads in Covers. I can't find the data on the web site and I'd like to do some analysis to test out my systems.

Go the <a href=http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/teams.html TARGET=_blank>Covers NBA Team Page</a>. From there you click on a team link and then click "Past Results" at the top of the page beneath the team's name.

[Newguyintown]

Can someone explain what the difference is between the first chart with the push frequencies and then what looks like the same chart that says MOV on it?

N G

[Ganchrow]

The first chart lists push frequencies ATS. In other words, for a spread of, say, ±3, the first chart indicates that there is a roughly 3.91% frequency that bet pushing. This can be extrapolated upon, so that one might say that for a spread of about ±3, there is a roughly 3.91% frequency of the favorite winning by exactly 3 points.

The second chart is simply a margin of victory chart. It indicates the historical frequency of the winning team's margin of victory being as specificed.

[raiders72002]

Ganch- That's very good information on push frequency. If you include 1/2, that is 6.5 and 7.5, and look for value instead of just push info I think that you'll find that 6 and 7 will be the key numbers in the NBA and 2 in the NCAA tourney. I haven't personally run the numbers but looked at charts from others.

Some say that there is value to buying 1/2 pt off/on 7 in the NBA and there's definitely value buying off/on 2 during the NCAA tourney.

Hi Raiders, welcome back.

I gotta admit I'm that I don't really understand what you mean about "include &frac12; ... and look for value instead of just push info". This is, after all a push probability chart from which one would have to derive the value of moving on to a given spread.

I've certainly heard that about 6s and 7s and NCAA BB 2s as well, but I've not seen any evidence of this in the historical data.

[gridironguy]

Great work here. Thx

[the_fredrik]

So, looking at the spreads 2-10, the push frequency varies between 3.5%(4 points) and 5.2% (9 points)

The actual MOV frequencies for 4 and 9 points are about the same though.

Do any of you see any reason as to why a 9 point push ATS should be more common than a 4 point push ATS?

If we don't, does it not make more sense to estimate all the push frequencies for spreads of 2-10 to the same percentage, maybe 4% or so? (Or rather 4.x%, where you can estimate x better than I can)

[newb411breaker19]

thanks a lot for posting the push frequencies for all the sports ganch, we all appreciate it very much

[THE HITMAN]

Interesting stuff...thanks

[Goldfisch]

I dont understand the importance of these numbers?

[St.Anger]

I dont understand than number.
hay i'm new member!!!
thank you!!!!!!

Ganchrow, thanks for posting this and your half point calculator, excellent data. How do you handle 1/2 point lines, for example if the line is 2.5, do you count a 2 or 3 point margin as 1/2 a push each?

If a game with a spread of 2.5 finished with a favorite margin of victory within 2 points of 2.5 (i.e., fave by 1, 2, 3, or 4) it would count as a (full) push for that M.o.V. (and only that M.o.V.)
