If I move it to maximum starting from the 11 teeth cog, it makes one supplementary "click" and it jumps 4 cogs (or sometimes - 20% - fails). If I move it to maximum starting from any other cog above 11 teeth, it makes one less "click" and it jumps 3 cogs, as written in the manual. It looks to me somehow inconsistent, so I suspect a wrong setting that I can not identify.

As about the tension of the cable - I assume that there is a maximum that I should not exceed, but I can not identify it. Low tension leads to failures in shifting to the mid range - 14 - 15 teeth cogs. So, I increase the tension in the cable, but how much? Maybe I go too far and this creates other type of failures? How can I identify the right tension of the cable?
The derailleur still has nothing to do with what happens. It is all about the shifter
