A tablespoon of oil is about what you needed in each cylinder. The rise in #5 is equal to the rise in other cylinders, so I suspect that a valve/valve seat is worn and not the rings on #5. It could even be a severely worn valve seal, but that cannot be known unless the head is pulled. And pulling the head almost requires you to refurbish the valves at a reputable machine shop, which is not cheap.
