Does anyone please know the complete orbital precession rate of planet Venus?

For instance Mercury's complete orbital precession rate is 575 arc-secs. a century, of which classical mechanical approxomation methods account for all except for 43 arc-secs. General relativity accounts for this 43 arc-secs anomalous precession. There are other models which account for this anomaly without GR.

I have developed a new gravity model. The model explains GR's predictions (except the anomalous precession) and makes new predictions. The model explains the complete precession of Mercury but only if the classical gravitational is not constant.

Your answer re Venus will be greatly appreciated. (I know that Venus' anomalous precession as observed is 8.4 +/- 4.8 arc-secs.)
