If the relative print quantity was high, then the 3:4 ratio is probably not noted as SPs even though some cards were printed at a lower frequency than others in the same sheet. In 1965, apparently Topps printed a lot of cards of Series 5, so the cards printed at 3/4 that of others are not noted as SPs. The high series (series 7) and semi-highs (series 6) most likely used a similar print pattern as that of series 5, but SPs are noted in series 7 simply because the quantity printed was much lower.
