As you have found, they are a "safe" starting point. As you get to know your equipment more and make records of your own settings you will be able to start making more accurate jetting adjustments based on your experience and records.
There have been lots of discussions on here about this subject. Whether you use a notebook or a spreadsheet or jetting software is a personal choice, the important thing is to learn about your equipment and what settings give you the best results on the stopwatch.
You can always try reducing the jet size until the engine pops, as soon as it does go back a jet size and make a record of it. That should be the optimum for that particular moment in time. The good thing about a rotax in my experience is that if you back off as soon as it pops then it does not appear to cause harm. Other people may disagree with this comment, but thats my experience.
Read Johns article, it explains a lot more and gives tips on how to check your jet size is correct.
