John,You are wrong, and right. 3 hours for 40p to 1 hour for 60p is 4.5 times bigger but a 350% increase, ie they have added 350% to the original 100%. You are quite right that the £45 to £80 is not quite double. Only 78%. Doubling parking permits I think gives a sense of what has happened in rather fewer words than explaining that the two hour zones have doubled and the all day zones have almost doubled, going up 78%.
