I did fix it. I replaced the error prone practice of using units other than time for estimation with the far more understandable process of estimating in hours, days, weeks, and months. That comes with an understood caveat that as the units get bigger so does the margin of error, and if people want more accurate estimates they need to allow time to break the task down.
