coverflyX is an experiment.  We aren't quite yet sure whether or not there will be an even amount of people requesting feedback on their projects and actually providing that feedback.

The "Balancer" amount you see when making a bid is determined by Coverfly, and can change at any time.  In times of high demand for feedback (when there are lots of people requesting feedback but not enough providing feedback), we may choose to increase the Balancer so that readers claiming feedback receive an additional token bonus, and thus incentivize more readers to claim projects.
