Reputation increase at temples

[mr_sir]

I'm playing an evil character for the first time ever, my character is a neutral evil assassin, eventually duelled to Kensai. Anyway, I'm trying to roleplay and that means taking some reputation hits every now and then. The problem is that I don't want to keep having to fight Flaming Fist soldiers and it would make sense that my character would pay off his crimes at a temple as she is the kind of character that does what she needs for her own benefit, regardless of laws, and this would be something that she might do in order to make life easier for herself. I was wondering though, does anyone know how much gold you have to donate to get a reputation point, and does it have to be in one go or is it cumulative?

1-2 500gp
2-3 400gp
3-4 300gp
4-5 200gp
5-6 200gp
6-7 200gp
7-8 100gp
8-9 100gp
9-10 100 gp

The money must all be donated at once as the amount given is not cumulative. I havent listen all the way up to rep 18 but if you are playing as evil that wont really matter will it.
