It's performance based (not entirely timeclock based), so it's more useful as a relative metric.
(Although, missed calls, etc, suggests actual availability problems separate from productivity.)
Which doesn't necessarily mean anybody was truly working 8 hours per day, but it does suggest that the top/satisfactory tier of employees averaged 4x the productivity for the same number of hours on the timesheet.
A 4x multiplier like that isn't explained by a normal distribution curve.
