Gyro sensor in LEGO playgrounds sampling rate?

I am trying to understand how the Lego playgrounds EV3.Template can be used to teach coding skills using iPads. I have got everything to work and indeed written half a dozen short scripts, but I running into difficulties with some elements.


An example the call ev3.waitForGyroAngleChange only fires after it sees a change of 5 degrees. I can work with it, say using it to control/manage a 90 degree turn; but not for a real time problem like correcting drift when driving in a straight line.


Is there any way I can decress this firing trigger? It works on the lego noob interface it seems, but not with swift playground code :{
