The current way of finding out whether you're hitting too early/late is the Error display, which may not be suitable for finding that out. Outliers skew the average, and it causes confusion to what it actually means (personally, I thought it meant the maximum error).
Seeing as Unstable Rate is "essentially the standard deviation of your hit errors", a median would be helpful to find where the standard deviation is based off, as well as having an easy number to see whether you're hitting too early/late.
