Monthly Trend
Observed Trend
Observations suggest decreasing agreement over the observed period, from 2026-05-13 to 2026-09-09. The estimated change over that period is -1.222 points on a 0 to 10 scale. Regression results place a 95% confidence interval around that observed-period change of [-2.389, -0.055].Regression table
The daily slope annualized over 365.25 days is -3.750 points per year, with a 95% confidence interval of [-7.332, -0.169]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
