Given that the development of deheaping that you get access to has no financial support (grant or otherwise), the software is offered with some limits. If you use the software, you use it with no guarantee that that it works exactly as the authors of it describe it working and think it works. In fact, because ideas have arisen and been dropped in development, the program contains code that is still there because removing it could have unexpected consequences and we saw no need to spend effort fixing problems we did not need to create. Rather, effort has gone into improving the estimation model and providing capabilities that that a user wanted and that we saw as increasing the utility of the product (e.g., better output and providing standard deviations of some estimates).
