Empirical timesleep is not enough

I find out that the empirical time sleep value used when preparing the detector saving parameters is not enough and does not guarantee the correct configuration in random circumstances.

As a workaround, the delay time needed in the configuration logic has been exposed as a controller property in order to facilitate the fine tuning of this value. However, this issue should be kept open until a final solution is found.
