Hi Guys,
I hope some of you looked the course PFTM by Anton Kreil. My questions are about video 21 of the course:

Why in the Endo analysis inflation has a short bias while in the Exo analysis inflation has a long bias?

How does he add up the scoring in the excel of video 21? If I have a positive score both in endo and in exo what will be my final bias?
Example: Endo for USD has a positive score so inflationary and so short. Exo for USDJPY also has a positive score so inflationary so long. Adding up the number you have a positive value but what you do? Short or long since the biases are different in the two kind of analysis
Many thanks in advance to whomever will help
