One of the crucial areas in understanding player ratings is understanding how to improve them. Solid practice plans can make an enormous difference in a player over the course of 4 years, so here are some helpful tidbits for setting yours. First, abide by the rule of diminishing returns. Spend no more than 20 minutes on an individual skill, or no more than 25 minutes on an offense or defense (apiece, not combined) and you will begin to encounter diminishing returns. There are very few reasons for a coach to break these rules, none of which you are likely to encounter until DI. If a player has maxed out his potential in multiple areas, it may be the right decision to go above 20 in some categories, but these exceptions are very rare

or you will encounter; either that or eliminate the "no" after spend.)
Also, especially at lower divisions, I frequently go over 20 minutes for categories. 20 full minutes plus 10-15 partially credited minutes > 20 minutes...
