Based on all-time mean agreement, this item ranks 80 out of 135 qualifying items and is at the 41.0 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 1.173 points per year, with a 95% confidence interval of [-1.361, 3.707]. This short-window annualized number is provided for reference, but the observed-period change above is the primary trend estimate.
