Post workout pump

Been peing stedy for about four months straight. I pe-ed about a year ago

for a few months but got a thrumbosed vein and quit. Anyway I’ve made about 1/4 inch gain in girth midshaft. From 4 3/4” to 5”. But my post workout ( jelq’s and squeezes) is about 5 1/4 ” midshaft. Any guess on how long it will take to have that measurement (5 1/4”) without ‘pumping’ up.
