 # To simulate the old 1.2.5 experience in 1.3, consider how much 
# experience one would need to enchant at the highest level. 
# In 1.2 and below, this number is 4625 exp, which is at level 50. 
# For the most recent snapshop (12w23a), this has been changed 
# to 825 experience (level 30). 
#
# Thus, we need to decrease the experience gained by a 
# factor of 825 / 4625 = 0.17838
