That's okay, you can mix it by hand and it will work without issue (it's what our ancestors did for thousands of years). But if you don't want to knead for 10-15 minutes, if you roughly mix the water and flour then wait 10 minutes and then start kneading you'll find it takes much less time and effort to get the same result.

what i was getting at is, that i can't really tell where the mixing stops and the kneading starts :-)

"mix roughly" gives me a hint though...
