ZHRmax = 6 based on 409 reported Southern-Taurids, assuming population index r = 2.3.
ZHR (Zenithal Hourly Rate) is the number of meteors an observer would see under a dark sky with the radiant of the shower in zenith.

Time is the middle of the interval in Universal Time (UTC), Solarlon is the position of the earth relative to the sun (equinox J2000.0), nINT is the number of reported observing periods and nSTA is the reported number of Southern-Taurids.
ZHR = (1 + sum nSTA) / sum(Teff/C) where Teff is the effective observing time and C is the total correction for limiting magnitude, clouds and zenith correction 1/sin(hR).
Data has been received from 63 observers in 24 countries. Thank you for your efforts!
