I was wondering if some one could help clarify one of my doubts, it may may a daft question

According to UKBA website, http://www.ukba.homeoffice.gov.uk/visas ... gevidence/
Under the section "What documents you must send" it says that you must a sequence of documents.
So here is my question:- Say I need to show the my income from my employment from my present employer from Mar 2012 to Feb 2013, do I need to ask my bank to get me each and every transaction from 01 Mar 2012 untill 28 Feb 2013
OR
Can I just ask them to print/send me the transaction (salary credit) for the days I have got paid, example I get paid on the 20 of each month so Can I ask my bank to send me statement from 15-25 of each month for the last 12 month (Mar 12-Feb 13) which includes my salary credit.
