Very Very Very Long PIP Assessment. I did a really good Assessment reply. Too Good?

I looked at the "increasing the automatic extension period" thread and people are talking up to several months, but I got my PIP reAssessment last August. I got the maximum extension and returned it in October. As usual I spent +80% of waking hours for the two months trying to do my PIP. I found a webpage that typed what you said and copied and pasted it all out. I'm worried I did such a good job they are rethinking my fit for work case 😕. It would literally work out I did something like two sentences a day working at it all day! It's all mental health related, nothing physical, and nothing has changed.

I don't answer the phone so if they have rung to give me an assessment I don't know (do they do that or send a letter first?). I've been in the system for a long time so I'm hoping they are treating me as a 'known' but because I complained in my Form about previous face to face assessments (like "eventually" eating, and having to do maths using my fingers and saying I couldn't do that in real life in a shop) that maybe this is a reason for the long long delay?

I live by myself and don't have friends and don't keep track of things, so the whole system is unknown to me. Might be a simple or complex explanation. Anybody advise?
