Thanks - your post is helpful, but unfortunately doesn't address my question. I'll leave it open for others to comment onI think I have already covered this point in https://www.canadavisa.com/canada-immigration-discussion-board/threads/work-experience-personal-history-and-fsw.576808/#post-7152579.
My advice would be to you to keep your 3 yrs work exp in the Employment History(the one that you can backup with detailed Letter or Reference) and move the rest to the personal history....
I don't have anything more to add here.
