Change rating growth process

Currently, every rating/attribute improvement is a gradual one, and as a result over time it’s easy to predict. This renders Advanced Scouting fairly useless for experienced owners. This results in experienced owners having a significant budget advantage over newer owners in addition to knowing the game better.

This does make sense for some (many?) attributes, but others should see a sharp increase once the player ‘figures it out’. A good example of this might be Pitches for hurlers - the guy is working on his curve ball for a while with little to no improvement and then he finally turns the corner and masters it. Perhaps an offseason workout regimen pays big dividends and instead of a 2 or 3 point gain for Strength it’s 6 or more.

Of course, not every player and every rating would have this sudden improvement, lending unpredictability to player growth once again.
