TOPIC: Project Hrs...

Hi,

I am having around 8500 hrs of project leading/managing experience and I am currently handling a maintenance project which is a having regular releases ( for last 2 years ), the releases having multiple functional projects ( new functionality ) and also a existing functional changes,

The question is:

Should I need to add as one project with the start date and the end date or each release as a project?

If I add as one project it is coming around 3400 hrs, is it OK to add like this or should I split by release?

I don’t wanted to make any mistake on the application..

Please guide me.

Thanks in advance,
Janardhanan..
