Unless any aggravating factors are brought to the attention of the court, (or very exceptionally, relevant mitigation), sentencing for speeding is paint by numbers. At the very bottom end of band C, you would expect 6 points, with the chances of a ban increasing as you creep further into band C. Below band C, you would generally need to have done something very naughty or very stupid (or both) for the bench (or SJ) to deviate from their colouring book of points.
Band B is 4-6 points for speeds from 31 to 40 in a 20. Depending on how well the bench paint between the lines, 37 would seem to be mathematically either at the low end of 6 points or the high end of 5 points. Technically the guidelines don't say to spread the point range out over the speed range, and if there was any reason for them to do so, the bench could award 4, 5, or 6 points for any speed in that range without having to justify going beyond the guidelines, but for the most part, it is paint by numbers.
I would suggest that being a "professional driver" who ought to know better is not information I would voluntarily be minded to put before the court.
There is no point going to court just to waste the court's time by putting on a school play of generic contrition.
