Based on that metric, Parra and roosters with the toughest draw being the only teams to play every top 4 team twice. Storm also max out on potential top 4 opponents at 6 given they can't play themselves.
Souths have a very soft draw for a top 4 team.
The Top 4 can only have a possible 6 games against the Top 4 give they were one of the top 4 sides, so it's better to go on percentages (i.e. Souths have 5 out of a possible 6 games vs the Top 4, and 11 out of a possible 14 against the Top 8).
If you go on percentages (assuming your numbers are correct)
