Not sure about I-Pace but LEAF has about 350 watts overhead to run the computer, cooling pump etc. during charging. Assuming same you will be using 1200 watts from the wall to get 950 watts into the battery or close to 30% loss.
Day in, day out I think I would use the timer to shorten the charge time vs an extended run on L1.
Having said that I did use my L1 charger on my LEAF back in the good ol' days when LAX allowed free prime parking and free charging for EVs. The L2 plugs were 4x over subscribed but you could park up a floor and use an extension to plug into the wall outlet next to the elevator. Easy to get a full charge when in Hawaii for a week.
