[Connect C# DgnPlatformNet] Proper way of setting custom Line Style

Currently I am using the following extension for setting an elements line style

        public static void SetLinestyle(this Element elem, string name)
        {

            using (ElementPropertiesSetter propSetter = new ElementPropertiesSetter())
            {

                if (name == "ByLevel")
                {
                    propSetter.SetLinestyle((int)SymbologyValue.StyleByLevel, null);
                } else
                {
                    int lineStyleIndex = LineStyleManager.GetNumberFromName(name, Ms.GetActiveDgnFile());
                    propSetter.SetLinestyle(lineStyleIndex, null);

                }


                propSetter.Apply(elem);
            }
        }

while this is setting the line style properly, it is not setting the line style Scale property correctly.

For example, my Line Style Scale is being set to 10000.0(UOR Scale factor possible from an Element.ApplyTransform()?) instead of 3.93700 which is the default value for the line style

I see that the SetLinestyle method takes in LineStyleParameters, but I have no idea where to get this value from.
