This is a fine question. Indeed, we would like to put sensitivity analysis into the Online Simulator. However, our immediate push is in building a new market simulator within the SSI Web v9 platform (Windows-installed desktop software). That simulator within SSI Web v9 will have the capabilities of SMRT, plus many more...all within a nicer user interface. We're hoping for a solid beta release of that before the end of the year.
I don't know when we will turn our attentions again to extend the Online Simulator's capabilities to include sensitivity analysis. We're a 30-year company, so we have a long range view on things. Unfortunately, that often means we might have something planned, but it could take multiple years to do it! I wish software development were easier and more instantaneous. But, the challenge is what also makes it so engaging and rewarding!
