Log your sessions; that is how Windulu gets to know you.
The advice is a tool. You remain responsible for your own safety.
Kitesurfing not allowed (inland water). An active wing and windsurf club.
The open water at Vlietland (Leidschendam) faces SW (225°). The safest wind directions to wing foil here are south, southwest and west (onshore or cross-onshore). With the wind from the north, northeast, east, southeast and northwest, it runs cross to cross-offshore: doable, but mind your position and don't go alone.
