Yes this is the most common way that most people follow. Probably the best also (at least for Germany i guess).
I follow the other way (better for me personally). You make a little hole in the ground, then put the potato and cover it with just a few soil. Make the holes in lines. The few soil will make them grow faster (in Greece many people harvest twice per year, me once because i am in a colder region). When they had grown enough, it is then you make the little hill and that is for two reasons. One for the potatoes to have humidity (the sun gets cruel, no need for extra warmth) and second by this way you remove in a convenient point, other wild plants that had grown.
Btw mine will bloom very soon, it has been more than a month ago that i had planted them.
thanks for sharing! at some point while growing we also add a little more soil from the side while also weeding
very nice yours is doing good!
I took a photo today. As you see it helps with weeding. I am not expecting many wild plants to grow from this point on.

they look great and just a little more flat
Each hole has its own little hill, not quite visible in this photo, maybe that is why seems more flat. If it was a line would seem different of course.
I zoomed in 👀 i can see the difference!
