When to apply for BC? - non-EEA spouse of A8 EEA national

[teekay125]

Hi, This forum is absolutely great. Thanks to all the contributers!

I have query about when I can apply for BC and will have to put in few dates, so please bear with.

April 2007 - I (non-EEA national) arrived in UK on work-permit
May 2007 - my A8 EU national wife joined me in UK
Nov 2007 - my wife started working and applied for WRS / I got FMRS
Nov 2008 - my wife applied on EEA1 / I applied on EEA2 application
Nov 2012 - my wife applied on EEA3 / I applied on EEA4 application
May 2013 - We have received the PR approvals / stamped

Question 1 - I understand 5 year Treaty Right Excercising automatically confers Permanent Residence for my A8 EU National Wife. When is this 5 year starting from - the date she arrived in UK (May2007) or date she registered under Workers Registration scheme (Nov2007)?
Question 2 - I understand after my wife's 5 years of excercising Treaty Rights + 1 year of HER holding PR (granted automatically), I am eligible to start British Citizenship process. Most important question for me is - WHEN CAN I APPLY FOR MY BRITISH CITIZENSHIP?
-> May 2013 - 5 year+1 from when my wife started living in UK?
-> Nov 2013 - 5 year +1 after her WRS registration?
-> May 2014 - when I complete 1 year of my holding my PR?
Please note my wife, is NOT intending to apply for BC, it is only me.

I appreciate you taking time to read this and many thanks in advance your help.

Tony
