What are the six speeds for the focal plane shutter in the later Speed Graphics?

The nominal speeds are:
30, 50, 125, 250, 500, 1000
I always wondered why they used a 50th when the other speeds were the ANSI progression. |

Earlier pacemakers had a 1/100 instead of 1/125. Not sure when they made the change.
