"ALL balloons were included during our calculation - even those that had not been donated yet."
I read that to imply they no longer are. If so that seems a little unfair as those servers got any balloons on the server included in the calc where as now there could still be a number of balloons left in storage and never donated leading them to not being counted. This would make it harder for the servers that haven't reached 100% to do so compared to those that already have while the glitch was active.
