Not seeing sufficient ad notifications per hour

Hi, I am from Mumbai, India and happy to be associated with Brave and its rewards program since July 2019. I am happy that Brave has activated the ad notifications and associated reward prog for android phone users since 15th October. But though I have opted to get 5 ads per hour , I am getting at most 4 ad notifications throughout the full day. I normally browse at least 5 hours every day at different times. Will the notifications increase over time ? hope to get a reply from support team., and thanks for the entire team’s great efforts and feedback here. I learn a lot about Brave here.

Thanks
