Experience - This refers to the age of the player. The categories/nomenclatures are:
-Youngster (Age 18-20)
-Hot Prospect (Age 21-23)
-Developed (Age 24-26)
-Experienced (Age 27-29)
-Old School (Age 30 or above)
Once a player reach a new category the XP gaining when training is reduced. -so training speed -XP gaining- remains the same in slabs of 3 years, meaning that once a Youngster 18-20 aged, reach the Hot Prospect category/slab, his training speed/xp gaining will decrease.
Think that every player gains XP differently, meaning that we have Fast trainers, and slow ones.
You can spot fast trainers on the market by listing the players by Value.
Remember that the XP gaining during the training sessions, was regulated in the old versions by the players main star, reducing the XP gaining progress a 15% aproximately, once a player won a star (at every star achieved = XP gaining 15% slowly).
But now the drills are what regulate the gaining, in a similar way. A drill affecting 1 skill, will have a XP gaining reduction (it will gain a -15% XP) at every 20% of gaining in the affected attribute, if affect 2 skills, at every 40%, 3 skills 60%, 4 skills 80 and 5 at every 100%.
Remember that, in the old version we had a training bar with 3 levels of trainings and that, once we completed the 99XP bar, the players won a Skill Point (SP) but since the game works in %'s every old skill point is a 4% (that's why we have the 4% gift actually).
White Skills gain x2 XP compared with the Grey ones.
New Positions and Special Abilities XP gaining are regulated by the main star yet, meaning this that you will train these faster as more younger, and lower in quality is the player.
