ORS Rating, Pricing and Booking Enginge

I have a question regarding the booking engine on the “newer” ORS (Limatambo):

If I have a city pair with plenty of demand and zero competition (not even connections), can I increase the prices up to an ORS rating of 1 without losing passengers, or is there a hard coded limit above which certain passengers will just not book at all, so the number of total passengers decreases?
