Haven't really tought about that but my own 2012 Civic Si needs R134 Top off every 3 years or so since it was new. When it starts to blow warm air, we flush and refill the system and it's ice cold again for another 3-ish years..If 4oz is all it took to be ice cold again, I would just keep topping it off for now until the leak becomes much larger. If these things are known to leak anyways, no point replacing everything now when the leak is super slow.
