Is there a way to boost alliance contribution points (ones that go towards weekly top 3)

Why I ask is over the past 3 days I have maxed out all donations diamonds and the ones that count down. They have never gone back to 25/25 as I have always donated before it gets to that but another member of the alliance just comes to the top out of no where takes the top spot. We are able to donate to tier 2 and I have donated to this each time. Is there a technology to research or building to upgrade that can affect this?
