I think the time travelling must have had an effect on the Mystics predictions.
Rain - arriving at 11
Actually arrived at 10, briefly, before returning in anger at 12:30
Lunch break - 40 minutes
Spot on - he must have known about delays in morning to bring break in line with his predictions (perhaps he had a magnet to make up for Terry's not performing).
Finish - 17:50
Actual finish about 18:20 - needs to have words with lesser mortals (drivers) about interfering with his powers.
