AWS RDS t2.medium CPU credits low although CPU not high
<p>I'm wrapping my head around this issue with the CPU Balance constantly going down although my CPU during this time is &lt;40% consistently.</p>

<p>I'm using a t2.medium with MySQL and according to this page, shouldn't it be that if I'm &lt;40%, my CPU Credits will increase?</p>
