Thanks for adjusting. Do you see the risk of others reading your guide thinking it contains researched facts, and start telling other managers about how things work based on what they read from you, which is just based on what you heard from others, who knows how they got their info or just made it up? And that's not even accounting for chinese whispers, which seems to be the case with your soft cap based on height. The way I read it, this manager is just saying height influences training speed of different skills, which is supported by research data. However, I know of no data that shows there is a cap for a certain level of skills that influence this. The influence of height is always there. Maybe it is confused with compounding factors like age or the potential limits, but those are independent factors.
Also I have no idea what exact BSP is possible, I only know I've personally seen higher BSP than 67. I have no data to support the idea that the number I know is a maximum, so why would I or anyone claim it as such just because you haven't seen any higher?
There has been plenty of research done and published (ie
(229484.1)), I don't see how adding a confusing guide of your own helps anything. Just add or ask to the topics that exist already. By adding more stuff you make it more confusing and harder to find good info for others.
