SitNGo Wizard 2 now includes a new equity model developed by Ben Roberts. The new model is an alternative to standard ICM calculations. The Roberts model is faster than ICM and, according to Roberts, more realistic.

You can view Mr. Roberts’ paper describing the model here:

A new algorithm for the approximation of ICM equities in tournament poker

A couple of 2+2 discussions of the model can be found here:
