Jack Sparrow, possibly not his real name, commented on yesterday’s Blunderful post:
The spread was -12, In your previous post you mentioned -16.5, can you clarify this please?
"In the last 20 NBA seasons, only one team favoured by 16.5 points or more has lost the game straight up."
Are we to use all double digit spreads or is there a cut off?The story about the straight up success of teams with a spread of -16.5+ was meant as merely an introduction to the world of big NBA spreads in general. Perhaps no one else found it interesting, but that the Brooklyn Nets came within a missed lay-up of ending a sequence dating back to 1998 seemed to me worthy of mention.
The line that I use for the Blunder System is shorter than the -16.5 of that story. Games of this spread are relatively rare, and don’t generate enough bets each season to make it worthwhile.
Jack asks “Are we to use all double digit spreads or is there a cut off?”
First, there is no “we” here – no obligation for anyone else to act on these findings at all. I’m simply sharing some findings with you all, free of charge I might add, for you to completely ignore or for you to modify and take the idea further.
Second, it’s important to understand that there is no single official line for spreads or totals on these games - witness Betfair’s habit of including several spreads for each game, or the differences between various sportsbooks in the US. The Spurs v Trail Blazers game of Monday night is a case in point. Jack says the spread was -12, the source I use had it at -12.5. You need to make your own choice as to what data to use.
Third, yes there is a cut off that I use, based on my choice of spread source, historical results and number of bets to be generated per season (for me, around 100 or so). Anyone else wanting to follow this idea would need to reach their own decision on where to draw the line (pun intended), preferably after looking at historical results generated from their selected data source.
Pegguy Wort, again possibly not his real name, commented on the initial post on this topic, asking:
What size of handicap do you look for when you're selecting games for this system?
The San Antonio Spurs are again a selection tonight, with a spread of -14 v the Denver Nuggets and a Total Line of 195.5. The Spurs are 3-0 for us so far this season on Unders.

Daft question but are you advocating betting in the Overs / Unders market or the handicap market for these?
V interesting post, involving a lot of data analysis/research.
I rarely bet on basketball, (which is probably a mistake), but was fascinated by the book 'Gaming the Game', which, as u are probably aware, largely recounts the tale, of a bent basketball ref, shaving points on games, he had bet on.
In trades across many sports, 'mug' punters want to see action, and many 'Mr Unders' type betting strategies will be profitable, as it seems the lines are inflated, to account for this public need.
Keep up the good work.
Best wishes.
