== Why it is called "anomaly"? == 

 The Pioneer "anomaly" is the same as "cosmological redshift" and that latter is explained by Einsteinian physics. So why it is still called "anomaly"? It is only anomaly in Newtonian physics since it does not have any explanation there but it confirms Einstein's physics. It's theoretical value is , where R is "Einstein's Radius", 4.3 Gpc. So its theoretical value according to Einstein's gravitation should be . Am I doing something wrong here?
