title: Why are Google Play installation stats so inaccurate?
body: <p>I noticed a large discrepancy in the stats reported by Google Play.  When I subtract totals for two consecutive days (Total User Installs).  I almost never get the same answer when I compare it to the Daily User Installs column? Do you know why it happens?  I posted my data <a href="http://artymiak.com/can-you-trust-google-play-statistics/" rel="nofollow">here</a>.</p>
