• For factors GREATER than 1.0, we multiply the rate of pacing times the factor. So a factor of 3.0 on channel id 12345 would mean that we are 3x less likely to block that request due to pacing than we normally would (assuming there is still budget available).

• Similarly, for factors LESS than 1.0, we also multiply the rate of pacing times the factor. For example, a factor of 0.5 on channel id 56789 would mean that we are half as likely to return an ad on that request than we normally would. 

• The MAX value for a Delivery Modifier is 5.0. Any value above 5.0 will be ignored (treated as a 1.0)
