Yes,the tank pressure will have an effect on the muzzle velocity,so does the hammer spring tension.Generally for a descent unregulated PCP Muzzle velocity vs Tank pressure will be a bell curve.A balance between Fill pressure,valve retaining spring and hammer spring tension will reduce the deviation in muzzle velocity between shots.Adding a regulator will fix one of these variables but adds to cost and brings added complexity to the design.In Precihole PX100 it has been done right and hence a good shot to shot consistency.Hope this helps.
