/// Example:
/// ========
///
/// Retire Control Unit - number of cycles where we saw N instructions retired:
/// [# retired], [# cycles]
///  0,           109  (17.9%)
///  1,           102  (16.7%)
///  2,           399  (65.4%)
///
/// Total ROB Entries:                64
/// Max Used ROB Entries:             35  ( 54.7% )
/// Average Used ROB Entries per cy:  32  ( 50.0% )
