Is the model parameters table use to represent a number, and this could be used repeatedly for convenience. For example, I would like to use a parameter to record the processing time, use this way could work. The parameter table could also be used in the Experimenter for looking for the optimal parameter, so it has lower bound and upper bound filed. But if I only would like to set process time for convenience. Is the the following to set the lower bound and upper bound into same value a correct way to use this tool?
