Penguin: Core, realtime and updated today
Penguin is now real-time. Historically, the list of sites affected by Penguin was periodically refreshed at the same time. Once a webmaster considerably improved their site and its presence on the internet, many of Google's algorithms would take that into consideration very fast, but others, like Penguin, needed to be refreshed. With this change, Penguin's data is refreshed in real time, so changes will be visible much faster, typically taking effect shortly after we recrawl and reindex a page. It also means we're not going to comment on future refreshes.

Just disavowing one domain most likely won't have any noticeable effect. You should disavow all of your site's low-quality backlinks plus any backlinks that have contrived anchor text intended to boost rankings for particular keywords..
I went from 100+ domains disavowed to 1 disavowed and haven't seen any difference.

Number four on the list of things to understand is that statistical analysis is an old technology and very likely has been superseded.
I think it's more likely that any lack of "useful information" for gaming the system is a side effect of Google's use of AI, personalization, etc., not the reason for Google's advancing beyond the relatively simple search algorithms of a decade ago.
