Based on all-time mean agreement, this item ranks 5 out of 135 qualifying items and is at the 97.0 percentile.
Qualifying items have 100 or more total observations. Higher means indicate more agreement and therefore a higher rank.
The daily slope annualized over 365.25 days is 0.729 points per year, with a 95% confidence interval of [-1.826, 3.285]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
