SR4759 is a slighlty slower burning pistol powder than H110/W296, being just the slow side of the 4227's, H and IMR.
In actual rate, they are likely VERY close. In any chart, there has to be one listed before the others. I'm thinking in terms that those ball powders and the IMR 4227's and SR4759 are closer than "kissing cousins". Of course, burn rate is not all of it, energy per grain also comes into the equation.
In one chart I just perused, AA1680 is listed as one slot slower than SE4759 & from use in small rifle calibres, 1680 is just a tich slower than H110/W296.
IMR3031 is MUCH slower.
