Sender-id records

I am considering checking for spf2.0/mfrom records when there is no v=spf1 
record.  Does anyone have stats on whether any of these actually exist?  
(I do not plan to check PRA given patent issues and general uselessness of 
doing so.)

If both v=spf1 and spf2.0/mfrom records exist, then I will give the v=spf1 
record precedence.  I don't think this is addressed in either spec.
