Now Mr Jones, the interesting bit, your master needs to be sized to you calipers. Or you end up with no modulation, i.e that little bit of extra pressure = lockup on the front.
So calculate and sum the areas of your caliper pistons, then work out the area of your master cyl piston.
Divide master into caliper cumulative and ideally you want a ratio of 27:1 but can go down to 23:1 any less than that is not a good match and you could lock the front quite easily.
