Open questions to be answered:
1. Is the number of attempts needed to lead a horse determined mathematically by the ride level, and if so how? Testing needs to be done to determine if this works by a random roll within a range determined by Level such as [0...(15-Level)]], or if it is based on prac percentage, with each try matching the the player's Ride% against a random roll from [a...b] where b is presumably 99 (or 100)? Test this at 99%. Alternatively, the player's Ride Level may be rolled against a random roll from [a...b] where b is presumably 7 (or 8?). Test this at 98%.
2. Does Ride affect the Movement penalties of various terrain types, and if so in what way? Also, how is the Notice penalty affected by Ride?
3. What do Levels 2 and 7 do, if anything?
