There are 'Energy Worm' and 'Energy Marker' features that can be 
enabled in the Hud so it's possible that the data you need is 
already being calculated.

To enable these features set <enable_energy_worm> and 
<enable_energy_marker> to true in the hudladder.xml file for the 
hud you're using

However, I had to comment out a couple of lines in the src code 
to get it to work every time - sometimes it was on the hud but 
at other times it was as though it wasn't enabled.

The src file to amend is hud_ladr.cxx and I had to comment out 
the test on ilcanclaw == 1 and it's closing brace.
