Beef supernoodles are indeed 10 syns on red or EE, only the low fat supernoodles are free and they don't do a beef one in low fat.
I think you are getting confused though - I have the directory from 2009, beef supernoodles - made up as directed, are 3.5syns per 100g on green and 9 syns on red. This would be 3.5 syns on EE (lowest value).
OP - you take the lowest red or green syn value for an EE syn value!
