Thanks for playing through the first day and writing it up. The minutes are there once birds arrive: the line beside the bar reads how many birds are in nets and in bags, and "oldest waited 20 of 40 min (net)" for whichever bird is closest to its own limit, which is 70 in a bag and 90 in a trap. With nobody waiting it only says "nobody waiting", so on a quiet first morning you saw the bar at its emptiest.
A big fall comes on a morning with an easterly wind and rain at dawn, so it depends on the weather. If you hit one, we'd like to know whether amber reached you early enough to close a net in time.
