2023 - Round 21 : Still Hard to Call
/Over half of Round 21 contests involved teams that are five spots or less distant on the competion ladder. We have:
Two games where the teams are separated by two ladder positions and where the lines are 18.5 points
Three games where the teams are separated by between three and five ladder positions and where the lines range from 4.5 to 50.5 points
One game where the teams are separated by seven ladder positions and where the line is 8.5 points
Three games where the teams are separated by between 12 and 15 ladder positions and where the lines range from 17.5 to 40.5 points
On average, the opposing teams are separated by 7 ladder spots this week, and the correlation between expected bookmaker margin and ladder position difference is +0.77.
That relatively high average ladder separation has translated into high average handicaps, the overall average coming in at 22.7 points per game, which is up by over 8-and-a-half points on the Round 20 average, but down by about half-a-point on the all-time average for Round 21s. It moves the all-Season average to 18.3 points per game.
