Proposals can be executed only if there is enough accumulated conviction. The threshold at which a proposal can be executed is dependent on the proportion of the funds requested relative to the available funds in the shared treasury. This relationship between the funds requested versus available funds means that the threshold at which a proposal can be executed depends on the state of the Commons at any given time. As proposals pass and remove funds from the treasury, the remaining proposals will become harder to pass (because they now represent a larger proportion of the shared treasury). As new funds are added to the share treasury the threshold for passing existing proposals will decrease. This provides some natural self regulation to the spending rate of the Commons relative to its income.
