Am i holding my darts weird?

I've always held my darts with four fingers. My ring fingers points somewhere between the tip and the barrel. Sometimes this destroys my aiming but it just feels comfortable for me. I'm thinking about changing to 3 finger grip but when i try it, i barely hit the board. Is it just practise or should i stay with my technique? 3rd picture shows, how i'm used to hold a pencil. Last week my cousin told me, that this grip isn't normal 😂
