It's a bit messy, hooking into the ICMP stats in places. But each time
squid receives an HTCP or ICP reply it counts as one ping. It looks to me
like it was intended for the up/down peer detection, but it has the
side-effect of falling nicely into the rtt calculation as a super-fast
ping, which then falls over to ever so slightly reduce the weight
calculation for that peer.
