Got the solution, 2 progress bars, one for the computer to estimate and the other for the task. Ok, 3, one to estimate the estimate, one to estimate, and one for the task. Nevermind, make that 4, one to estimate the estimate of the estimate, one to estimate the estimate, one to estimate, and one for the task. Slight revision, let's make that 5, one to estimate the estimate of the estimate that estimates the estimate, one to estimate the estimate of the estimate, one to estimate the estimate, one to estimate, and one for the task. After further thought, we just need one to estimate how far out an infinite regression can go and then just not worry about the task.
