Tommy's works out their standardisation on the group of boys that sit the tesr. Chances are that this is a pretty bright subsection of society and so standardised scores will probably be lower than if they were being set against the norm.
Pates work out their standardisation so that the 160th top scorer gets 240.
I initially thought the same as you Milla but a thread posted back when the results came out alerted me to the fact that Denmark Road's standardised score was going to be lower than Pates.
Have you heard anymore on what sort of passes got into Tommy's, am quite desperate to know for next year?
