I can’t say that surprises me too much. Cost correlates pretty strongly to the complexity of a project, and complex projects should take more staff evaluation.
You might also be seeing offsetting effects—bigger budgets may have some efficiencies in evaluating good proposals; they may also attract more low-quality proposals that must be rejected. It could wind up being about even, efficiency wise, over a fairly large range.
