Hi,
some power values from the IM seem to be here:

For a layman it's strange how some of the reported powers seem to drop after ~120 mins, is this due the SRM drift or GPRS coverage or race course or smthng I can't imagin?

You can get the datafiles at http://www.srm.de/deutsch/IronmanHawaii.html , so you can check for dropouts.

I think part of the power output change is due to course profile and tactics.
