As others have said, you're probably working somewhere between the two. Full profile tools give exactly the right radius at the root (and the crest, but that's irrelevant for the table on my website) of the thread. Sharp tipped tools are really only for very fine pitch thread: for example I've never had confidence in grinding the right radius on a tool for cutting 0.4 mm pitch threads, so I just use a sharp tip there.
If you're using a partial profile insert tool or a home-ground tool with some arbitrary radius, then the in-feed distance will depend on that radius. Having said that, it'll be somewhere between the two values (full profile and sharp tip) shown in the tables on my website.
I've added an explanatory note on the page to help future visitors.
