Attitude data push to ground terminal using sphinx and SDK3

Hi all,

I am sphinx software for Bebop2 Simulation and SDK3.

Through some of the posts i came to know that bebop2’s attitude information will be sent to ground at every 200 milliseconds. But when i am trying to estimate the time between two successive
" ARCONTROLLER_DICTIONARY_KEY_ARDRONE3_PILOTINGSTATE_ATTITUDECHANGED", I am not able to see a constant time difference between two successive samples.

Is this update rate is constant throughout the flight or whenever there is a change in attitude?

Thanks in advance.
