Multicast:confirming interpretation of mstat command

Question:

I see that multicast activity for the first hop (27 pps, 222/222 = 100%). Then other two hops displays 0 activity for multicast traffic.

I am just wondering whether this could indicate opportunities for optimization or that is normal?

SwitchL3#mstat 10.2.17.3 10.2.49.15 239.254.13.31

Never mind. I see that the mstat lists the layer 3 hops along the way to get to source, so if it is 0% it just means the router in the path is not providing any multicast traffic.
