Question regarding pitch

[TOViper]

Hello!

 

Attached I have a track of the Viggen going for an inverted Immelmann.

As you can see I had disabled SPAK, and went down using a slight-to-moderate elevator input.

At about ~600km/h you see me reducing this input just a little bit, but then (just a tick later), the aircraft suddenly (like in the form of a step function) increases AOA, which also can be heard due to the high AOA alert.

 

Was this the moment the pitch gearing increased the elevator surface deflection?

And if so, was this a step-function in the real aircraft, or was it more of a gradual characteristic?

 

Thanks for any info on this and kind regards,

TOViper
