No, I have just been assuming things. Some of the stability code is... strange to me. It could probably have been documented better. Or it could have been designed in a... clearer fashion! 
All I know is that the Persian UP affects the actual stability value - immediately and irreversibly. But I haven't considered what this means for any parameters that are stored and used going forward. It simply never occurred to me.
