Question about the algorithm's difficulty factor

I saw your blog post describing the algorithm used in this app and I wonder about this difficulty factor. In Anki there seemed to be the whole issue around "ease factor", so much that one of the most used addons modified this. It's an outdated issue with the new FSRS there though.

So what I'd like to ask is, how does your current algorithm behave when you fail a review many times, then start being succesful again? Do the initial failures mean you're forever cursed with short review interval for that specific review, or will it fix itself? I see the algorithm described, but I don't know what values the app plugs into it.

Could you perhaps give me an example of what happens to the "difficuty" parameter when you e.g. fail a review 5 times in a row, then answer correctly 5 times in a row, compared to another review where you answer 5 times in a row without any failures?

Much appreciated!

For posterity: the blog post detailing the algorithm.

As you can see from the post, the "difficulty" only goes up and down based on the current review. So once you start getting it right multiple times in a row, the only thing that matters is how many times you get it right (and how much time occurs between each correct answer), not how many times you got it wrong in the distant past.
