Murray wont win a clay master series and wont win RG and therefor no matter what kind of math you are working with is no big threat to Federer's nr1 record.
Only Djokovic and Nadal have the potential to have crazy clay seasons while Federer with some early loses in the big ones would be in danger of not breaking the record.
Grr, Murray is still in a better position now than Nadal, or Djokovic.
Federer - Emperor of the Slams, King of Hard, King of Grass, Lord of the Australian Open, Lord of Wimbledon.
