In output of "show ip bgp sum", does PfxRcd mean prefix or path?

R1 #show ip bgp summary
BGP summary information for VRF default

Before addpath, for one particular neighbor, it only sends ONE best path for one particular prefix. So PfxRcd = PathRcd. But after BGP addpath, the behavior changes. Multiple paths can be sent for one prefix to speed up the convergence time. So the meaning of this number is changed to "pathRcd".
