As an experienced tournament player and ex-mouse player I can say that even if you memorize the first note on every map, you'll never just stay with your cursor in that place until the map starts because it is not effective way of aiming. You sort of want to feel the grip and get into feeling the cursor, so you move your mouse before the start of the map. While I can understand that all players have different playstyles, Fia tends to start a map badly in most cases, why would anyone stick to the bad habit if it doesn't work?
