That all sounds correct.
Perhaps try stirring the grounds once its a bit wet (still some water in the bowl).
2mins brew is also about right and the only other thing, the amount of coffee grounds, also seems on the money (a tblspn per cup). You could go to 4 scoops for 500ml (some merit in a scoop for the pot).
If you decide to send it back to its dark home at the back of your cupboard, I know where it could get a more useful life...
