I didn't mean to argue against what you've stated. I am sorry if my post sounded so. I only wish to understand the logic and rule properly as it stands at the moment.
Surely, it cannot be assumed that a person will land into UK immediately on the day the visa is issued. There will always be a time lag. Basically below is what I am tring to understand:
Applications that fall short of the five year continuous period
In some cases, applicants may have been granted five years continuous leave, but due to delayed travel will not have spent five years continuously in the UK before their current leave expires. Caseworkers may count the period between entry clearance being granted and the date the applicant entered the UK towards the five years, provided this period was not longer than three months.

Thanks again for your time and help.
