I'm reading Apocalypse Delayed.
It doesn't say why Brown chose 360, but he went from 604 BCE to 1917.
Barbour thought Brown was 2 years off, and went to 1914.
Russell was convinced with Barbour's reasoning, and kept it after their split.
I like the comment in the Revelation Climax book regarding the overlooked 0 year factor:
"Providentially, those Bible Students had not realized that there is no zero year between "B.C." and "A.D." Later, when research made it necessary to adjust B.C. 606 to 607 B.C.E., the zero year was also eliminated, so that the prediction held good at "A.D. 1914."
So, it's not wrong light - it's just bent. And science has demonstrated that light can be bent.
JeffT, if you have demonstrated repentance, you may be reinstated, but your tithe rate will be 30% during probation.
