I have been practicing since four o clock
she's written for this magazine since 1992
pourquoi pas "she has been" dans le deuxieme cas alors que l'action n'est pas terminée.
Ma pensée va vers une action d'habitude pour le second cas.
Merci d avance.

L'action est continue et a débuté à quatre heures.
She's written for this magazine since 1992
Oui, She has been writing... marche aussi.

Ihave been practising the piano since four o'clock.
Here we focus on the duration of the action which started at four and it's still continuing. that means the action is still in progress and how long this action has been in progress
SHE 'S WRITTEN TO THE MAGAZINE SINCE 1992.
HERE WE KNOW THAT SHE STARTED IN 1992 ,BUT THE ACTION IS NOT UNDER PROGRESS.
we can also say she has been writing ......since1992.
to make this tense easier to my science students here in Morocco, i used the Maths notion of intersection to teach the present perfect. eg intersection of past and present.
Good luck
