///
/// 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% )
