Hi Hui,
I hope you are doing well. I have already sent this question (Base line) to him and since I didn't hear back from him and I think I may need these for my job, I posted here. If you have not heard of baseline, that means such a thing doesn't exist at all. I am the one who misunderstood.
Conversion line: When I was in the interview, one of the interviewer "who was a lady"
talked about conversion line and charts...!
Sorry for not explaining clearly, I know Chandoo is a guy.
Best Regards,
Guity
