I'm really enjoying the World Tour mode, congrats once again!

- Do the CPU players ever progress/regress in skill or do their skills always remain static no matter what?
- Does a CPU player's current entry ranking (or maybe other factors such as current form) have any impact on a CPU player's performance during a match? E.g. if CPU Player X had fixed skills would it make any difference if he was at that moment ranked 250 as opposed to 140?
Thanks in advance!
