Nevertheless, I still think it is not a bad idea to reveal the decimals of the skill of players. Probably instead of having a manager seeing their own player's decimals by paying, it would be better to make the decimals public and make everyone see the decimals of their own players and the players on the market.
If revealing the decimals is too detailed, then we can probably just cut each level into 3 (as in the box scores) or 5 sublevels.
Displaying sublevel might help in accelerating the game since it could make a newcoming manager feel their training progress more clearly (so that their training seems to improve every week, not just pop every 2-4 weeks). Of course, it might be even better for the training to make daily updates, so, for instance, managers can see a player improve in IS 0.07 points per day, rather than 1 point per 2 weeks.
