So you are having a total amount of 8 hours per day, right? That’s should be enough for a while. I’d keep doing what you’re doing for a couple of weeks and then try to increase time gradually. But I insist, keep an eye on force. While you are not destroying your head at the point that you have to take unnecessary reset days, it’s fine. This is the sweat spot IMO.
There’s a link for the picture of the silicone cap in the page one of this thread. Maybe it can be useful in your search.
