Methods and apparatus for adjusting model threshold levels are disclosed. An example method includes determining volume estimates corresponding to a total number of users that satisfy a model threshold; when a ratio of (A) modeled users that satisfy the model threshold to (B) a sum of the modeled users that satisfy the model threshold and deterministic client device users does not satisfy a minimum ratio threshold, increasing the number of modeled users; when the total users that satisfy the model threshold does not satisfy a total volume target, increasing the number of modeled users; and updating the total volume target based on the increased number of modeled users; generating an adjusted count of users; and a model threshold adjuster to adjust the model threshold based on the adjusted count of users.
