Quoted from razorsedge:That defeats the entire concept of putting washers in the first place, which is (intended) to increase the surface area with the given tension on it. Despite this if the clear is not cured (or soft), it is only going to increase the size of the squished area.
That's partially true. I agree that a larger diameter washer helps distribute the force over a wider area. But, the (star) posts themselves are not flat on the bottom. If a washer the same diameter as the post it would be better than a post alone. Is it enough? I don't know.
Here is a picture of the bottom to illustrate:
