Describe the bug
Sometimes the standard deviation printed out by the pendulum_demo is wrong.
When the Min(13459 ns), Max(83599 ns) and Mean(24672.386000 ns)
values are like in the brackets, how can the standard deviation be 135818791.307981?
It just happens sometimes, sometimes the value is as expected around 1000.0.
To Reproduce
Run the pendulum demo multiple times with all the necessary priorities:
ubuntu@ubuntu-rt-1:~$ pendulum_demo -i 1000
Expected behavior
That the standard deviation matches the other values.
Screenshots
