Writing stuff down in the order in which it occurs is a good rule. It is a particularly good rule in the opening paragraphs of your story. Triply good if the stuff you want to work in happened just a few minutes earlier. . . .
Yet I managed to miss, in the first draft, that I was opening with the heroine musing about something that had just happened. I shifted the opening back a minute and had it whap her upside the head, but how did I manage to miss that while wrestling with how to open the first draft?
So I eliminated the past perfect from the opening. Always be wary of using the past perfect in your opening. It's a warning that you haven't started your story in the right place.
And it's more elegant if you notice while writing not revising.
