A bunch of BS is involved if someone is trying to tell you any STS will do more acres than 2 8820's. That's assuming both 8820's are running and not under repair. Most 20+ year old combines aren't the most reliable. I'd even bet that a bright shiney new STS couldn't keep up with two good running 7720's. The STS would catch up when the old machines needed attention though.
