All you can do is try some different. Just know that if the mount wholes are off center only 1 or 2 degrees you would never see it but will know it when adjusting your optics. Try another dot and if stiill off your smith screwed it up.
Got to watch out with smithy's too. Way to many of them them are much more like oil change and tire change guys that say they are mechanics???
They get there degree at some community collage and there a smithy?? NO just a parts swapper . Some know where to draw the line ,some don't.
