When I am just cruising or riding the twisties I use one finger on the clutch and one on the brake.
If I am approaching a intersection I place two fingers over the brake and use all four on the clutch.
It's just more comfortable for me to cover the brake and clutch with one finger each. If I get into any situation that I may need to brake quickly (heavy traffic, residential streets, etc.) I will increase the number of fingers accordingly.
But I am FAR from an experienced rider.
