  1. Good’ (ICC > 0.75) or ‘excellent’ (ICC > 0.9) behavioural stability scores are indicated with bold font and a * or ** respectively. 91 days was the maximum number of days available for each season. CI – confidence interval. There was a maximum of 13 unique combinations for 1-week (as each season had a total of 13 weeks); 78 unique combinations for 2-weeks; 286 unique combinations for 3-weeks; and 715 unique combinations for 4-weeks
