This is the problem.
The Commission were supposedly working to PL "guidance" for breaches of PSR which are 6 points for breach plus 1 point for every £5m over (so technically, we should have been done 9.9 points)
If you assume that the tariff remains unaltered then what happens if the appeals panel find out that we are £30m over (or they are instructed to)?
Not saying it will happen BUT personally I wouldn't hold my breath for any big points reduction
(In fact, it may be better to think "ok, it's -10 and go with that mindset)
