That 60% figure surprised me. Seemed quite high. So I just scanned my mail logs for unique sender envelope domains of mail classified as ham, for the past 10 days. I then did TXT record lookups on the lot of them. 146 out of 242 of them have SPF records. Which is *exactly* 60% here too... I repeated the experiment for the past 100 days and it was 51%.
