How were the load times calculated? What point is considered the start and end and how do you factor in variables such as site js? Furthermore, showing this as percentages makes it look good initially, but if you start at 60 seconds, then the page load is still terrible.

It's also worth pointing out that the load times throughout 2016 were abysmal yet advertising quality has been consistently poor for a number of years. What triggered this rise?
