Yes, this estimation is fairly accurate - it is reestimated after each iteration. > If so, is it possible/ > feasible to reduce this execution time? Yes, and sometimes by quite a lot.

Yes, if you are running the default CRMAv2 method (please always provide your code and sessionInfo()). You can specify the subset of arrays to be processed by doCRMAv2() via argument 'arrays': http://aroma-project.org/blocks/doCRMAv2 Thus, you can launch doCRMAv2() on the same data set on multiple machines where each machine runs a different range of arrays.
