I was quoting the advice given to magistrates... there is a table that gives a speed range over the limit and the suggested action. The magistrate can then take into account "aggravating or mitigating circumstances" based on that they set their sentence.
The speed bands go up to 31-40mph over suggesting 6 points or up to 56 days + fine + costs, by my calculations you were, at least 48 over... that's outside the guidelines. So expect a ban of at least 56 days + substantial fine + costs.
The seriousness of the offence is why all are suggesting you seek the advice of a specialist in this field.
Remember these are guidelines only, depending on how serious the magistrate views the offence, should it come to court, you could find that the ban and fine are much greater or with a good brief much less.
BTW it is not how much you are earning now that they will consider it will be how much you are earning if/when it comes to sentencing.
