- It is more accurate. I have replaced the Stirling approximations of the factorial function with exact factorial calculations.
- It is faster. Several coding changes were made as I re-wrote this from Perl in Python. Calculations for factorial and binomial coeffecients are cached.
- It is more reliable. Google's App Engine has better uptime performance than the Imp Lair servers.
- It is easier to use. Calculations have gone from three steps down to two.
