Great questions Ken. The answers are:

The Bird reads a reflected power of about 2 watts
The power output reading on the Bird stays a constant 100W, while the Omni 
reads 25 watts, decaying to 15 watts over 2-3 seconds. Then stays steady.
Collector current correlates well with the Bird readings and stays steady.
