All right. Maybe something was actually changed by the manufacturer.
The power distribution in terms of the size of steps or the number of heating levels is another topic (I think this post is intended for pulsations within a given heating level).
This "power distribution" also puzzled me, because it is kind of non-linear / disproportionate looking at the electric power, but using the board I get the impression that it is practical from the point of view of needs:
use level 1 only to keep the cooked food warm;
levels 2-4 for slow cooking (boiling), covered;
levels 5-10 basically only temporarily as we "go down" from the full power needed to bring the food to the boil, to the state of slow cooking (perhaps someone cooking uncovered at these levels achieves "slow cooking");
levels 11-13 for frying with fats / oils;
levels 14 and P for warming up the pot with its contents (at the beginning of preparing, cooking, frying), and most often for boiling water in the kettle.
I guess this is supposed to work like that, as well as a logarithmic potentiometer to adjust the volume

only not exactly logarithmically, but according to some other rule (not necessarily according to a specific or continuous equation)
In contrast, the size of the steps / number of levels is always difficult to determine with "quantified" / digital control. Even in audio devices, the volume controls are differently tuned in this respect, especially in the low adjustment range (e.g. in silence or "sleeping", 2 may be too quiet and 3 too loud, while there are 30 or 40 levels in general)

As for the instructions, unfortunately, as you write, I agree 100%. They do not even provide general information on whether there is continuous or pulse regulation (they also have a problem with answering this question on hotlines). I myself was very stressed before the purchase as it will be with this pulse regulation, but it turned out to be good. With protection and logic, from the very beginning I chose among discs with more power levels, but here too the information is ambiguous, because for a part of society the disc has only 9 power levels, even when they are graded every 0.5, so in fact they have e.g. 17 levels ...
