If you like the taste of the eliquid when you get it, then vape it and do not be concerned about steeping. This is all about how you perceive the taste, with the equipment that you use. If you think the eliquid needs a little bit of time, then steep it. Try it again every week or so, until you like the taste. You will soon find out how long it takes for various eliquids and flavors to taste good to you.
My daughter and I like some flavors straight out of the mailbox, even though the vendors and other vapors recommend steeping. We both also have flavors that, for us, benefit from steeping for varying lengths of time before they taste good to us.
Don't forget to shake the bottle before filling or topping off your topper.
