Wet landing distance private operations

[chr]

Hi everyone

I know that there was a lot of discussions about this but when I started to read all of those posts I finally get lost. I have quick short question to confirm my way of thinking

JET LANDING ON DRY RUNWAY :

private - I can legally go to airfield with LDA available the same as unfactored from aircraft manual (It is not a good idea I know about it but let's put this aside for a moment)

commercial - LDA available must be at least as unfactored landing distance from manual multiplied by 1.67

JET LANDING ON WET RUNWAY :

commercial - factored dry distance must be multiplied by 1.15

private - here I have a problem - manual says that on wet you must first determine factored landing distance and than multiply it by 1.15 but this is required for commercial and what about private ?

Thanks for clarify
