Форматирование вывода System.Diagnostics.Stopwatch и Measure-Object с помощью PowerShell 5

Windows 10 64-бит. PowerShell 5.1

Формат вывода System.Diagnostics.Stopwatch и Measure-Object с использованием PowerShell 5.

Я зацикливаю команду System.Diagnostics.Stopwatch и выводю Elapsed.TotalSeconds в массив для измерения производительности набор команд. Я обрабатываю массив с помощью Measure-Object, удаляю пробелы с помощью $_.Trim(" `t"), строку с select-string -pattern и добавляю новую строку с if match regex, чтобы получить это и немного больше: 

Count    : 10
Average  : 0.35949785
Sum      : 3.5949785
Maximum  : 1.485631
Minimum  : 0.1970544

Count    : 10
Average  : 0.33406021
Sum      : 3.3406021
Maximum  : 1.0060256
Minimum  : 0.2100706

Есть ли лучший способ?
