Is there still an anomalous precession in Mercury's orbit that GR doesn't predict? I was reading through the Wiki pages on tests of relativity and I was curious about this section.  Am I interpreting it correctly?  Is there still about $1.21''/\text{ cy}$ of precession (Total Predicted: $575.31$ - Total Observed: $574.10$) that are not predicted by GR?  The reference is from 1947.  Does anyone have a more recent measurement and/or prediction?
Edit: My apologies. I transcribed the difference between the observed and predicted incorrectly.  I've updated the question with the right values.  Sorry for the inconvenience.
 A: The wikipedia section on the precession of Mercury's orbit is in serious need of an update. The presented observational data is centuries old. Its main reference is the Clemence paper from 1947. Since then the astronomical data have been updated to give a GRT prediction of 42.98"/cy. Clemence gives a slightly higher value. The other two relevant numbers are the Newton predictions on the precession without the GRT effect and the observed precession. The difference of these is the anomaly to be explained by e.g. GRT. The Clemence paper relies on Newtonian calculations from 1911 and observation data from 1863. A modern prediction of the total precession including the effect of GRT is given in this open access paper. The reported number (575.31"/cy) is also given in the wikipedia article (just added extra ref). I am still searching for modern observational data. The 43"/cy number is far too important to rely on very old observations. There must be more modern information. I hope the Bepi Colombo mission will also address this. I will update this answer when I find anything.
