Hmmmm, seems my reply never turned up in the list.
Anyway, the method mentioned by Jordi was what i was looking for. Turns
out i was looking in the wrong place.
This way i can try and find out if i can maximise my batter some or
other way. (although i will probably have to wait til after my exams...)

Thanks

Rene
