OP here — wow, did not expect this much response! Thank you all for the thoughtful replies on WELCOME Introduce.

To answer Admin: I started tracking everything in a spreadsheet from day 1.

Quick update: I will post a proper update thread soon. Thanks again for the evidence-based discussion — this is exactly why I posted in a science-based community. 🙏

100%. My provider said the same thing about WELCOME Introduce.

+1 to cory_ATX. Especially the point about "The first month are the hardest..." — I have seen the same in my own experience with WELCOME Introduce.
