For those of you who are interested in regression calculations, here is how one system works.....
For ATS calculations one takes the scoring margin of a team (at least 5 games should be played) and subtract it from the opponent's scoring margin. Will list each game below.
1) Alouettes -3.62 Bombers +3.38
We get an average scoring differential of -7/game (-3.62-3.38) for the Als,...then we add 3 points for the home field, which gives us a line of Alouettes +4. That is the difference on the field so far this year. The actual line is now +1....so we would be looking at taking the Bombers, right?
WRONG!!!, we go opposite of our calculations for two reasons,...Number 1) Things hardly ever stay as they have been going and 2) Vegas has these same calculations as I do and if they are putting a different line to the calculated line, they usually know better, they are trying to attract money to one side. The indicated play would be the Alouettes. Normally in my experience we do this to play dogs only and away dogs in the past have performed much better than home dogs in regression calculations. In the NFL, after 6 games, this hits about 57% of the time, which is very acceptable in the NFL....most of these plays will be contrarian plays and if you use a filter such as going against the public you can increase your win rate a couple of percentage points. In other words if you have an indicated regression play but the public likes the dog as well at >50% of the betting population, then that game would become a no-play....it basically is an ugly dog system. I use a differential between the Vegas line and my line of >=3.5 points for it to become a play.
The other calculations for this week's games.
Home team Away team My calculated line
Scoring differential scoring diff.
Edmonton +3.50 Sask +3.57 Edmonton -2.93
Ottawa +.44 BC +.22 Ottawa -3.22
Calgary +14.12 Toronto +.89 Calgary -16.24
Remember we are using this to play dogs only, as using this to play favorites has not worked in my experience. With a required differential of >=3.5 points between my calculated line and the Vegas line, the only indicated regression play this week is the Argonauts.
As the season progresses I use the last six games ONLY to calculate a line and I delete the highest and lowest game points scored and allowed to get a 4 game average and then do my regression calculations.
To see how that works in the Argos/Stamps game. I'll post the numbers.
In the Argos' last 6 games, here have been their scores
25-33
27-24
27-38
24-41
9-21
38-6
We delete the 38 and the 9 in the points scored column (highest and lowest scores). Then we delete the 41 and 6 from the points allowed column.
That gives us 103 points scored and 116 against, then we divide by 4 for an average of 25.75 points for and 29 points against per game an average -3.25 points/game differential.
For the Stamps their last six games played:
29-10
23-30
27-10
60-1
41-24
21-17
We delete 60 and 21 from the points scored and 1 and 30 from the points allowed, which gives us 30 points/game for and 15.25 points/game against or +14.75 game.
We take the Stamps points/game differential of 14.25 and subtract the Argos differential of -3.25 to get 17.50 points/game differential and add 3 points for the home field. Our calculated line is Stamps -20.50, which is >3.5 points from Vegas' line.
Regression says take the Argos.
