	% chance given for solo study at given amount of time. % chance cannot exceed 99%.
	Every additional 2 hours increases the chance by 5%. Shortening the time decreases the chance by 5% every hour
	Add between 10 and 30% if the character is studying in an equipped library or laboratory.
	Add 5%/category difference if studying with a higher level spellcaster that does not know the spell.

As an example, a first level magic-user has a 25% chance of learning a new spell on his own after 8 hours of study. If he studies with a level 3 magic-user (one category higher) who does not know the spell he has a 30% chance of learning the spell. If he decides to spend an extra two hours studying with the mage his chance would improve to 35%. Once a check has been failed the character can attempt new checks after every additional given increment of study. Therefore, if the first check is failed, the character can make a second check after an additional 8 hours of study. These eight hourse would also increase the chance of success by 20%.

Note that studying must be done in two hour increments. It is assumed that while travelling the character can study for no more than 2 hours per day (unless travelling on a sailing ship, wagon, etc.). A character can spend a maximum of 4 hours per day and still have time to do other things -- such as shopping, following plot hooks while in town, etc.
