What is the Maximum Score of StringSifter?

[Ramaaaaaa1]

For finding the malicious strings in a binary, I have used StringSifter. When I presented the sample scores StringSifter gave, my supervisor questioned the StringSifter maximum string score possible. Though I searched for it, I couldn't find a source that would answer my question. Would you be kind enough to tell me what the maximum possible string score using StringSifter?
