PSTEC Positive to remember magic sentences

Hi,

Is it a proper application of PP to remember the 4 sentences in Magic Sentences?

My mind seems to go blank when sally says “ok here is the magic sentence…”

My statement is “I easily recall all 4 sentences when guessing the magic sentence”

Also I noticed some doubts creeping in because I did 2 rounds of PP with this sentence and tried the Magic Sentences again and there was no change in recall.

Thanks,
Scott
