How strong is the perihelion precession anomali of the earth

My suggestion is to find it for Mercury, look at the formula, and compute a ratio based on the mean distance to Sun and the eccentricity.

Because, if computing from nil, the chances of success are about zero. Mercury at least is observed for long.

 

Or maybe in a paper about glacial ages? It has an influence, depending on if the perihelion is in winter (now) or summer for the northern hemisphere where most landmass is. Though, precession of Earth's diurnal axis is faster, so that would suggest a period over 100,000 years.
