I clarified the sparring requirement since we had a question this morning...
Time. This is your total time (in minutes) it takes for your vampire to become a Grand Master, create 13 vampires, spar with 13 vampires (winning is not required, but you must let the animation play out and not cancel early), and cure 13 vampires. Make sure to plug in all necessary information into [Lena's spreadsheet]. Keep in mind that with a vampire you won't have x number of days until the Sim becomes an adult to work with. Just make note of how many times you pass the 8 a.m. on Sunday mark for weeks, and then keep track of days and the time.
