In that case, the "projections" were plain simply wrong: Almost everyone was (successfully) made to believe/expect that "SPF kills spam". The real purpose is to detect forged/wrong/illegal senders and to - at least - do not backscatter/send error reports/... in that direction thus reducing the overall mail amount and hassle.
