Yes, if the slop adds to one, then you can pull a bead across the dividing line and cheat.
On the silver orb, I actually fudged to:
to make the second rows tighter. According to my calculations they were going to be too loose for comfort.
For my fudge, those rows drop down the sphere by a smidge to make them longer, and come back up to the right place again when they reach the dividing line. Just enough for two more beads, but a surprisingly small cheat.
The slop on the next orb is very small in comparison, far from adding up to one. So no fudging will be needed I think.
Another interesting consideration is that the more rows you have, the more rows are adding slop, so the tighter things need to be.
Yes, I'm doing one more of these in between Radiolarians.
