Application for PR

Hi all,

I (we) are completing the EEA (PR) forms for my wife's DCPR.
I am a little stuck on Section 10 C = Integration
This part I don't understand, and correct me if I am wrong,

I was exercising my treaty rights, ie, working in another member state (Germany), from 1st July 2013 until 1st October 2013.
At that time, there was no requirement for the test of moving "centre of life"
This requirement came in I believe on January 1st 2014.

In EU we submitted all the required documents, job details, renting accommodation details, etc, and my wife was issued with a 6 month EEA family Permit, allowing us to travel from EU to UK.
We arrived in UK on 22 October 2013 before this "centre of life" requirement came into effect.
When we arrived in UK, we completed her EEA2, in December 2013, and this Residence Card of a Family Member of an EEA National, was issued in March 2014, valid through to March 2019, (5 years.)

I am confused what to write in the box 10.15 C Integration, as I believe this did not apply to us, as our applications preceded this requirement.

Can an informed admin, please advise ?

Many thanks

GW
