Based on that report in the Telegraph showing UK Sport's expectations, shooting and judo have reached the upper limit of their expectations (1 medal).
Of the other events where we have won medals so far:
Gymnastics won 1 - expected 1 to 2
Canoe 2 - expected 3 to 4
Cycling 4 - expected 6 to 10
Equestrianism 1 - expected 3 to 4
Rowing 3 - expected 6
Swimming 2 - expected 5 to 7
So in the categories where we've won medals so far, we've won 15 compared to a minimum expectation of 24. Obviously still plenty of medals to be won in those categories and ignores other categories where they expected to win a medal and didn't.
