GEODYN has a capability that freezes the measurement editing status after a certain number of iterations. So, if you freeze at 5 iterations, it would use the measurements accepted for the fifth iterations for all subsequent iterations. We could make this approach a little smarter and freeze the measurements if only a small fraction of them are being edited.
