I don't know how it is with the scores, bet when it comes to ratings...
For example for me, when I guess correctly, it gives me a ~0,6+ team rating boost, mostly on OD and ID and about the same with the offence rating, which depends from the attack that I'm using.
When my guesses are incorrect, I lose about ~0,3 team ratings.
About focus and pace guessing - in my opinion, the advantage they give must be even (for example 5 pts both)., because they both have the same nuber of variants to guess. If it was like 6 for the focus and 3 for the pace, then everything would be normal with the different advantage given.
