That is my concern too. My maths script is very good—I put considerable effort into the equations I write and as such the numbers, lines, and symbols turn out very good. On the other hand, no matter how much I studied lettering (regular and cursive), I don't really recognise any difference beyond what came of the added patience of my age. My letters are the same, they are only tidier. It was truly terrifying (sorry, my twenty-some teachers...) and only got better because I slowed down.
