Number of points for vampire= capacity (-1 if under 5, +1 if over 8) + point value of drawbacks (if any).
Disciplines: Basic= 1 pt. Superior= 2 pts.
Titles: 1/2 pt for primogen, 1 for prince, 3/2 for Justicar, 2 for Inner Circle (based off of the @ vote = 1/2 pt system), 1 for '2 votes'. Nosferatu and Gangrel paid 1/2 more points for titles in the basic set and perhaps in the expansions as well... Large Ventrue seem to get Primogen free, if they have no other title.
+1 bleed and +1 hand damage are 2 pts @.
Clan specific bleed or hand damage is free.
+1 stealth was 2 pts for Lucretia, and 1 pt @ for Muaziz and Rebekka (this seems undercosted).
No Bloodhunt votes for this vampire is apparently 1 pt (this seems undercosted).
One can generally extrapolate from the system listed about what the presumed costs of the less common powers are. For instance, Gunther seems to pay 2 pts for his untap ability, while Masika pays 2 and 1/2. Anneke pays 1/2 for being able to block any actions after others fail. You get the idea.
As for Drawbacks, look at the number of points the 1 capcity caitiff has who has it; that's the number of points it's supposedly worth. Of course, some drawbacks (like Uriah winter's), are a lot more painful in play than others.
