Important to note-the hourly rates reported from observers is usually converted to the ZHR (Zenithal Hourly Rate) which is the rate for when the radiant is overhead in a dark sky with a limiting visual magnitude of 6.5. Observing from a City and the suburbs will not meet the second criterion hence one will see less than half of the hourly rate or nearly none from a light infested location. I observed for a while and saw about 60/hr from Tucson which has a dimmer sky than most cities due to lighting ordnances to protect the nearby Observatories which was about half the reported rate for the same time my limiting magnitude was about 4.5-5.0.
