To be honest, I've not noticed this pattern (not saying it's not happening, of course!). The reason I suggest pumping out content is because Steemit isn't organized very well. Your feed (and everyone else's) is essentially content diarrhea...as soon as you post, there's probably hundreds of others that will post within minutes.
To get around that, I genuinely believe you have to play a numbers game. I'm trying to aim for at least three or four posts a day. If one of them gets hit by a whale, it makes it worthwhile. But only posting one decreases my probability of visibility.
That's just my thoughts on the matter...
