Can you please not spam the community with nonsense? You aren't asking a question and you are posting the same thing 3 times within minutes, even though it's not exactly the same. If you formulate a normal question and just put the three thing in the same post, you may get an answer on all three, if you make it clear what you need. It is all related to PI, so the chance is that someone with this knowledge can answer all 3, instead of missing any of your questions.
Please mark any helpful or correct solutions as such. That helps others find their solutions.
