I've worked with several EMR (Electronic Medical Record) systems that communicate an absolute metric shit-ton of redundant data for no reason other than just because and bad programming habits. Banking and Healthcare thrive in redundant redundancy.
I said nothing about the application and you already know everything about it.
Seems like I spent quarter of century in this business for naught.
There is a huge waste of power on the internet with data going back and forth for no good reason.
