@swolny Sorry to bother you again but I would confirm again about the total depth in the calculation. Shouldn’t it be the sum of all depth? Which is (5+15+30+60+100+200)=430? The maximum depth is 200 cm but I think it is not the total depth in the weighted calculation.

Also, thank you for the advice on the 0 cm layer. I did both calculations with and without it and the results are not affected so I agree with you to simply exclude it.
