Licho, but then you are not using your auto groups at all.
My advise:
1-4 Combat units.
Early game 1 is your scout, 2 your first group of lings etc
Late game you can put all casters in one group, this is very vulnerable to emp though.
You can put an active creep tumor on group 4 for easier creep spread.
5 - 8 Hatcheries or all hatcheries in 4 and 5+ queens.
