Wrong. These numbers have been a constant for about a year, not a "random boost". I invested a lot in art, updated my page, thumb, and I've been advertising constantly and regularly since then. The algorithm literally threw me down, there is no excuse for that.
Be careful saying things like that to devs, you can end offending them. Many work very hard to get what they have. I've always learned that we should respect the hard work of others, never devalue it as "random boosts".
