170 vs 180 degree shutter angle?

[TW Foley]

On Kodak's website, for Double X film, it shows an exposure-footcandle chart for a 170 degree shutter. the light meter i have is geared for a 180 degree shutter angle, and so is my camera. how many stops on my lens should I open or close to compensate for the difference between 1/48 and 1/50? Or is the difference insignificant and wouldn't really matter?

Pretty much insignificant. I don't even much sweat the difference between 1/48th and 1/60th.
