Rob already answered your question, and it should be obvious:

A receiver gets MAIL FROM you, allegedly.  The only reliable 
info from the receiver's POV is the sending IP, and your SPF
record when you publish a policy.  

Therefore your SPF record has to permit all IPs really sending
MAIL FROM you, from a receiver's POV.  You can permit more IPs,
e.g., if that simplifies your SPF record, but not less.
