I was researching a paper "Test of General Relativity from 3 dimensional orbital
geometry of a binary pulsar" by VanStraten , Bailes et al.They have mentioned
that they expect the precision of a value to increase as a function of
t^3/2(t=time).I dont understand how a given observation's accuracy can improve
as a factor of time in mathematical terms. Are there systems whose accuracy can
be expressed as a function of time??
