This is something I have thought about a bit for my table.....
And I think I will keep the refresh rates the same... Which was Edge refreshes every game session or after a signifigant amount of time.....
of if the session covers several days worth of actions in the game, they can expect to grain a couple of points, but they also know that it will refresh to full the next time we sit down to play, no matter where they are in the current Run.
