I'm curious if anyone can estimate the relative importance of the radiation and general relativity corrections.  Including radiation must result in a higher initial electron velocity to supply the extra required initial KE.  But it's been too many years for me to remember how to calculate the magnitude of the radiation, and I have no idea what general relativity does.

The Larmor formulation shows the energy dissipated by radiation from a 
decelerating charge.  An E&M text by Purcell was used by Dan Schroeder 
(Weber State) as a reference source for a talk he gave at a meeting of 
the AAPT (1999). Here is the text he spoke to.

The final paragraph is titled Quantitative Treatment of Radiation,

where he diagrams the Larmor formula for this case.
