-21? Dang! Do you hate her that much?
I haven't done that path, but you need less than -21 or lower for some stuff with her on the Tony cheat path.
Meanwhile, on my main saves I'm over here at 20/21/21 or 20/16/21 if I don't want to cheat on Lara even with Angelica.
(I'm 95% sure those are the max combined positive points you can get while meeting the 16 and/or 21 point thresholds for all 3. Getting 21 for both Lara and Angelica seems to currently be impossible, even if you ignore Erica.)
