Doesn't the 10% growth (but actually just 2 more users) thing sound like vanity metrics? I don't see how 2 more users is that great by making it seem bigger?
Better than nothing, better than non-paying users maybe but it reminds me of a Publishing company i used to work for who once internally touted their 100% rise in video revenue (ignoring the fact they had 5 or 6 times the amount of products released at the beginning of that month and had no video product with a projected profitable lifecycle).
Covering user acquisition in unneeded and transparent vanity metrics seems to me to be unnecessary, especially when you are asking customers for brutal reality.
