Yes, I am always amazed at the way professional darts players can almost
instantly re-calculate the double they need when the previous dart has
landed
in the wrong bed.

I suppose that because they are practicing for hours every day, it is just
second nature to them.

Ditto for snooker players

Although with snooker the players often make lengthy glances at the
scoreboard, so their maths cannot be as instant as darts players. And snooker
doesnt have certain shots that double or treble each score.

Most people can add the numbers 1 to 7 pretty easily.

Treble 14, treble 17, double 12 is not quite so straightforward.
