Another minor issue . . .
ER -- I've been working on a story that involves a lot of this. It's a very large craft, with many levels of varying Gs. IN IT, I mention that walking around the axis of the craft is relatively easy, whereas walking along the axis will result in a mild drift of motion (to the left or right, depending upon the artificial North or South direction of travel) for the person taking the walk.
And that formula calculates well in MS Excel.
