China league has just completed with the following result;
Home-Adv Chart N3 +15 / N1 +23.5
Form Chart N3 +27.5 / N1 +31
China has a small league of 15 teams and thus more consistent results spread as the middle range teams are less, hence a +ve instead of -ve Form Chart. There is a good consistent swing for both chart in the +ve direction.

I hope to proof that for small leagues approx 10-15 teams, the charts tends to give more positive rather than swing pattern for Home Adv Chart and -ve (near 1) for Form Chart, for 16-20 team leagues.

Will update as more team complete their season.
