Adbrite concern: what is the best starting bid in Adbrite?

Hi Folks,
I saw the highest bid in my site is getting high (0.36$) comparing to my starting bid (0.05$). Should I increase the starting bid or not? Increase or keep it the same, which one is better for us? I saw a blog in blog.adbrite.com, it says advertisers are looking around 0.20$. Do u think should increase from 0.05$ to 0.20$?
Looking for your experience-base advice.
Regards,
