Update French translation for statistics page - Needing help 😊

[ldmpub]

Hi,

I'm trying to understand and improve french translation for app stats page.
Yet I have performed 3 changes, I'm 90% sure 😁.

Can you please help me perform next improvement (see yellow part of the screenshot below):

As far as I understand, the 'Total' label here is not a total but a "time difference" (ie subtraction).
I suggest to change it to short label "Différence" or "Résultat" for french (I'm still in reflection yet) but do I need to change (extract for the default / en language file):

string name="statistics_total_tracked_short">Total (1)

or

string name="statistics_detail_total_duration">Total (2)

or does this change requires to add a new string in the translation file? (3)

These proposed changes can also be "ideas" to improve other translations and main / English labels in particular.

In french 'Total' changed to 'Écart', I hope the key statistics_detail_total_duration is not used in other app screens than statistics near 'Retard' / 'Avance' labels?
