I have a (hypothetical) question, since this was probably researched before (or not?). So, for the most part, people go and train their plays up to skill level 20. Sometimes some skills go beyond 20, but very rarely are they purposely trained above that. I looked a bit, but couldn't find info on that, but are skills beyond 20 increasing the effectiveness at the same rate? How would a player with 25 JS fare against a player with 18 OD? Provided he still had 16-18 HA/DR, 12-13 PA, 10-13 JR and 13 IS (just made up numbers, basically all around player, but with 25 JS)?
Would the effect be similar to what a 10 OD player defending 17 JS player would be?
Anyway, that would be (afaik) very unconventional and possibly a way to surprise opponents, but I have no idea how exactly these skill beyond 20 work, if they lose in effectiveness, if the effect compared to OD is linear (18OD vs 25 JS = 10OD vs 17 JS) etc.
If there is already a great topic/discussion on this, please feel free to link me there.
