I am only talking about the pass. It depends on what you consider spam.
If I define spam as commercial email then 90% of the spf pass are spam.
Examples are staples, Fredrick's of Hollywood, natural vitamins, etc.
The actual email by humans were mostly from aol. I looked at less than an
hours worth and this was over 2,000 that passed spf.
It seems that the majority of the adopters of spf are commercial email
marketers - mailing offers to list. Not sure how many are optin or verified
optin.
But for sure 90% of the email that passed spf was advertising.

I'm using guess "a/24 ptr/24 ?all". Here are my current numbers:
Spamminess Spam Ham Key
0.992 6 0 HReceived-SPF:failure
0.154 11 96 HReceived-SPF:none
1.000 438 0 HReceived-SPF:softfail
0.923 76 10 HReceived-SPF:unknown
0.999 10172 19 HReceived-SPF:neutral
0.027 435 24834 HReceived-SPF:pass
0.999 65 0 HReceived-SPF:error
Note that neutral is a .999 spam indicator.
Pass only gets .027 for non-spamminess, with ~2% of the SPF
passes being classified as spam.
What sort of numbers are you getting John?

I have been mirroring spf pass on my mail server. To my disappointment
90%
of all email passing SPF are from email marketers better know as
spammers.
The other 10% is mostly from aol.
I may decide to filter on passing spf as opposed to accepting spf.
