I am sorry to hear this and not knowing the court room or traffic stop particulars, I suppose your "youthfulness" relative to us "oldtimers" might have worked against you more than anything.
A speed reduction to 60mph would have been much more helpful, if they wouldn't grant the 3111-a because in PA, no points are accessed for speeding up to miles over the PSL.
I still believe it was a good attempt on your part and even so, one can't win 'em all (that certainly applies to me also).
Be safe...
