How can I find minimum execution time in PowerShell?

Question

I have been using Measure-Command in PowerShell to time the execution of a Python script:

Measure-Command{C:\Python27\python.exe script.py}

This displays the execution time in a number of forms, including TotalSeconds.

In order to minimize the effect of overhead, I would like to run the script 10 times and find the minimal TotalSeconds value across the 10 runs. Is there a simple way to do this in PowerShell?

Use Measure-Object command, like in this SO answer:

C:\PS> 1..10 | % { Measure-Command { C:\Python27\python.exe script.py } } | Measure-Object -Minimum

Count    : 3
Average  : 
Sum      : 
Maximum  : 
Minimum  : 00:00:00.0095165

It looks like the Measure-Object command needs to be Measure-Object -Minimum TotalSeconds, but otherwise this works well. Thanks.
