Never, >since he will find also that 1.9(1) is quite excellent, or even 2.2(3) : >all deviations are within 3 e.s.u.s. Obviously that 1.9(1) and 2.2(3) are much worse than 1.72(3). Relative error (sigma/bondlenth) for them are 0.1/1.9=0.053=5.3% and 0.3/2.2=0.137=13.7%! But 1.72(3) has 0.03/1.72 =0.017=1.7% - seems to be good. Best wishes, Maxim
