Yes, maybe. I would say maybe 4h per day on week days, and some more hours on weekend. And then the last couple of weeks I spent even more than that, maybe upwards 10 hours, or more. But then I was at an immersive course, where we where only allowed to speak french. When I travelled France I also lived a couple of days with an old retired wine consultant. He only spoke french, and when I got back from day trips in Provence, I would sit with him and just talk and drink wine. That also helped a lot.
