I tried to explain that in [this comment](https://github.com/w3c/sensors/issues/198#issuecomment-303650408). HW sensor samples some physical property at 'sampling frequency'.

Polling is an application level concept, developer can create repeating timer and poll data from sensor buffer, access on demand without timer, or wait for interrupt from interrupt controller and get readings at output data rate frequency.
