Your appproach seems to be exact enough, as long as you do not render very large control trees and you don't use server controls that do all their work in an overridden Render method (unexperienced server control authors tend to do exactly that...).

In that case, there is actually a way to render the actual rendering time ;-) Just use a HttpResponse.Filter object to fill a placeholder with the elapsed time. These filters are applied after the web form is rendered and before it goes to the client.

If you need this just for development, search for trace.axd, this will give you a lot of details not only about timing but also the request context, control tree structure and page size.
