Is it possible for the impact count to go down on a SE site?
I have a fairly active profile on Ask Different. The people reached count from my various posts touched ~1.4m around a month ago. But today I happen to notice that the count has gone down to ~1.3m.
I have always observed this number going up. The uptick was prominently visible when the number was in hundreds and thousands.
Is it ever possible for this number to go down? If yes, what possibly causes this? I don't remember deleting any of my posts in a long while (last 3-4 months).
Has some recent change in SE engine caused this (corrected) count?
