When chemists compare rates of reactions carried out under different conditions they often compare rates near the beginning of the reaction. What advantage does this offer?

It is most advantageous this way. At the initial stage of a reaction, the concentration of the reactents are equal to the original original concentration of them... Hence it is a known quantity. It is much difficult to determine their concentration, when the reaction is under progress. Some reactions are so rapid that it is almost impossible to ascertain the concentrations. Hence the rates are compared near the initial stages of the reaction. This was elucidated in 1911 by Leonor Michaelis and Maud Menten, in framing the Michaelis Menten equation for steady state kinetics.

Reactants are at their maximum concentrations. As reactant concentrations decrease, the observer sees best the dependence on concentration of each species.
