Hi, Don.
Are both using the same packet size and packet cargo? Also, the dynamics of PingPlotter's methodology (sending out multiple packets to the same host with different TTL) and MultiPing's methodology (sending out multiple packets to multiple hosts) sometimes causes different responses by the router that's dropping packets.
The difference between 2 lost packets and 24 probably falls outside the edges of what can reasonably be called statistical variation, but it would probably make some sense to make your interval a bit shorter (ie: 5 seconds) and see if this keeps the same 1:10 ratio.
Where does PingPlotter first show packet loss?
There are numerous reasons why the packet loss might be different. Your best bet might be to use PingPlotter to try and find the problem (make the trace interval much shorter, and then try and locate the problem router), and then use the problem you find to possibly determine why MultiPing is reporting more errors than PingPlotter.
