You are right, i didn´t notice it a lot, i suposse there are differences; but for me, two positions training at V league in Spain, i couldn´t appreciate it. I´d like to see analysis for level 3, level 4, 5, 6...As i told before, i only could find for level 5, logically you´ll train faster with a level 6 trainer than level 5 and slower with a level 4, but there are no any more solvent studies that the manager experience and for me, the biggest difference is their price:)
Thanks.
I think you would need a lot of data for this study and it would need to be long term... Let's say, for example, that the difference is 1 week of training per season (it is probably not, but let's just go with the example). Even after a full season, you would probably not notice a difference between a level 4 and 5 trainer. And don't forget that sub-levels would also play a role and make it difficult to do any analysis.
