My understanding is that a highly spherical electron implies the electron has no sub component parts. Knowing the exact radius of the electron doesn't change that, it's knowing there is no variance in the radius that is important. And again, I was only commenting on what was being commented on here. I don't know if the experiment was also highly accurate. But people here were commenting on the precision and calling it accuracy.
