I think there might be some savings here, less wax is heated by the candle, so less will evaporate. But I don’t know enough about candles to know whether that’s significant.
At best this gives a marginal increase in duration for the price of twice as much wick.
Those are special candles. Old timey candles dripped wax everywhere.
