Hi Karl and all,
Short periods will be very good. It does not make sense to go below 2 minutes, since it will then already matter in which direction in the sky you are looking. A certain feature in the stream will pass over the observer in ~1 minute. Also, there is nothing like a fixed grid in time for ZHR averages. More averages are computed for periods where more data are available and fewer when there are fewer meteors. I would tend to propose 3 minutes for the period lengths during the peak time. Shorter if activity is really outrageous.
Note that the visual form allows to give three decimals for Teff. Please make use of these and round Teff to three digits, i.e.
1 min = 0.017h
2 min = 0.033h
3 min = 0.050h
4 min = 0.067h
5 min = 0.083h
6 min = 0.100h
7 min = 0.117h
8 min = 0.133h
9 min = 0.150h
10min = 0.167h
Good luck!
Rainer
