DNA - MRCA statistical interpreation

I have had two suspected family members tested with the Paternal DNA 46 marker tests, as well as myself.
The one relation has an MCRA of 10 and the other has an MCRA of 14. All three tests were done in 2010. and the haplogroup for all is the R1b.
I think I understand that the second person, for example has a common ancestor with me 14 generations ago - At 25 years per average generation, this would be about 1660. Is this correct? Also, what reliability could one put on this data? would it be say +-10% variance on the average date or generation?
I would like to fix a time period when this common early ancestor was born?
I hope someone will be able to answer this question for me.
