It depends on the strength of the hair spray and your 'do'.
If I'm wearing my hair down, it's just past my shoulders, and with loose curls, then I spray lightly, as I'm looking to 'set' the curls but have movement still.
If I'm tossing it up in a pony tail and slicking my hair back, I use more to hold the strays, but leave the 'tail' alone.
Hope this helps.
Significantly more help than wikihow was...
