Okay, so the actual reason here is that you're lazy, it's not a lack of information. I get that — I'm lazy too — but don't cite vague concerns about administrative budgets when you could literally search "how much should a nonprofit spend on administration" and find 237947209847 articles about evaluating that. There are entire organizations like GiveWell dedicated to answering that question and they do in-depth research so that you don't have to.
Chrissake, you have no idea how much we deal with this working at nonprofits. "You are nefariously concealing information from me!!!!!" "Have you tried looking at our website?" The answer is basically always no.
