We are in the UK, and my sis has competed under many different scoring systems!
The least deductions I can remember her getting was a 6.0 out of 6.4 in level 5 bars (
YouTube - Level 5 Gymnastics). That isn't the routine that went 6.0, but the same moves. This routine actually placed her 4th out of about 45, and the 3 above her had kips.
Her friend once hit a 6.4 vault (out of 6.4). Haven't got a clue why everything was scored out of 6.4!
Under the new open-ended code, she was scored:
Vault- 11.4 (13.0 SV)
Bars- 11.1
Beam- 10.3 (wih a fall, but ended as county champion)
Floor- 11.3
AA- 41.9
I think those are right!
