I did a bit of a search for "difficulty" in the board and came upon a post that mentioned:
"from Pro-10 to Master-10, the CPU skills aren't modified"
I'm in the second year of a career that started as a Junior. Lately, I have been playing Pro-10 difficulty. The issue I am having is that the CPU's play can be random. Meaning, I find that I have a tough time with an unranked opponent and then wipe the floor with Alcaraz. Is that normal on Pro-10 difficulty? I am considering bumping up to Master-1, but the above statement seems to indicate that nothing will change.
Any insight?
