IPv6 packet losses - 20% normal on traceroute6s?

I'm just curious, as I have been seeing this for a while now.

When I use the 6tap IPv6 traceroute service, it seems like I get a
consistent some 20% packet loss. Pinging the same host from the same
site does not show anywhere near this loss.

Even routers very close to 6tap's server (first and second hop shows
one out of three dropped packets each) show this problem. Tracerouting
back to 3FFE:700:20:3::1 (first hop from 6tap towards me), while not
giving much information (only three hops being listen, as opposed to
six the other way) still shows a rather consistent 33% loss between
UUNet's router and 6tap's.

Is this considered normal?
