You dont have to trust me at all.  everything is mutual understanding.  Im  expressing  exactly what you just  said, BB marin saying things and  don't back them up with data, is it lies and myths when he does not?? . When someone else come out  with data or a saying on issue. He  a give statement with no data how can we say who is right  and who is  wrong? because he is  owner/coder. He is soley right.?
 I cant remember the manager name but he told all  the system to run 2~3 zone , he told us he ran it on Nt level, gave all sort of data.. I tried the same  data, bought  a team just for his data and  2~3 didn't work. Im out of  2-3 million.. I can not call him a lie because he is a NT coach and respected. Maybe it was my team vs his team level of exp..  I did learn some things about 3~2 zone though from that data. So it wasn't all bad
Which  is #2 in what you just said.  I have not contradicted  BB marin or the Bb guide.  To study the game  and findout things  when someone  is giving data it doesn't make it factual, it  just  a make  for that team performance. 
I want to understand  where is the data from Marin beyond words to  support the performance, there is no data in manual guide? If I use the same guide and find some more things  to expand the issue, that does not make it untruthful.
 Not confuse  thing here. Thats just my team doing well and the data supporting my team, Will what i did ,work for all. That  is were the issue lye.
 Writing data to support  all ideas has to come from BB Marin(not just words in the wind) . All you can do is say from  experience,experiment  which can be corrected overtime by BB marin but with no data# by him  how, it build confusion. conflict. But what we  can do is gain understanding  so the information is not all false, if  you can gather a understanding and transform it to universal for all.
 Pr guys are just like trainers under another name. Build to his job duty for  your team . Pr  guy help you  sell out to the cap in some cases.  Pr mean  more than just nothing, its a small % of money  in choice you choose for your team..   I would  tell a new comer get Pr guy before a trainer. That how I feel about it. Its help revenue for future things.
If you dont build to the job(specality )  of the PR  guy , You will get nothing, you hinder his performance. Btw I don't go beyond level 3 with anything on the game. It very affordable and  its get results
 But  there a lot of boost  when team 1st start. I feel its important to get the most out of them
