Abstract: This work is aimed to discuss the accuracy of the results of repeated measurements for gravity base points now undertaken by a number of seismological research groups in this country. It gives the formulas for calculating the accuracy of gravity measurements along multiple paths with a number of gravimeters, especially, the formulas for the method of  “single path and three repetitions”  which is now widely used. Certain inadequate ways of estimating the errors, being too low, have also been pointed out.
