I know a player that got over 80 percent scholarship and she didn’t play for 2 years and transferred. Although one would think the amount of money would be proportional to play time it clearly is not always true.
The method I have heard of is that a player will receive 50% or so the first year and if things go well the first year the amount will be increased year by year. Otherwise, the money that would have gone to the increases is available for new recruits.
