Your right. If a % of impressions is all that is required, then your
method would be perfect. Although when a site reaches the level in which
larger companies and/or media buyers are purchasing impressions, the "% of
impressions with no guarantee" is not going to fly. Don't get me wrong,
your method is very good for what you wish to accomplish, but it is not
scalable for a site that puts a heavy burden on advertising revenue.
