There are a few spelling typos in the manual and a calculation error in the Soil Model Wizard. Change "then" into "than" with the letter "a". See the red boxes below.

The sentence "
A large depth is defined as a height of soil coverage on top of the pipeline greater then 8.6 times the outer diameter of the pipeline." is not correct. It is not given in the NEN 3650-1 Dutch code and the fixed value 8.6 x DOUT is not always true (approximate range between 5 x DOUT and 10 x DOUT depending on the variable soil parameters (see also NEN 3650-1:2020 article C.4.2.4.3 "Bij grotere dekkingen (H > 5 à 10 x de leidingmiddellijn) geeft de methode van Marston hierdoor geen goede benadering meer van de passieve grondbelasting.")). It is better to change the sentence in "
A large depth is defined, when Qp is greater than P'max.". So, the lowest value: MIN.VALUE(Qp,P'max) should be used for RVT to be exact.
The calculation in the Soil Model Wizard in Ple4Win needs to be changed regarding to this calculation condition!

For the purple boxes a dot is mssing at the end and for the orange boxes the colon ":"-symbol is missing.
