The first observation revealed by Mr. Hikino was the size. An ordinary polvs consumer wouldn't easily be able to tell the difference. The 7-Eleven edition is actually much bigger than the one's they sell in Goldilocks.
The 7-Eleven edition looks like it's 2x bigger than the Goldilocks edition. The ones shown in the photo above are of the same flavor, which is cookies 'n cream. Even the bits of cookies looks much bigger in the 7-Eleven edition. The ones sold in Goldie looks smoother, as if the powder and cookies were grinded and pounded by a machine.
The price of the 7-Eleven edition is P10 per polvs compared to P6 of Goldie. Goldie doesn't actually sell it per piece, so we just computed how much one would cost if you buy a box of 20 (P120). So that's 120/20 = 6.
Goldie edition is half the size but more than half the price of the 7-Eleven edition. But how does it taste? Is the P10 polvs worth buying? Members of PGPCP conducted a polvs taste test to know if there is a relevant difference in taste. Both polvs were sliced to be of equal size as to remove size bias and make it purely a taste comparison. The results were astounding. It was a mass conversion of skeptics to believers. The 7-Eleven edition was a landslide winner; It simply tastes better! Why does it taste better? We don't know yet. Maybe it's because the Goldilocks edition is just too compressed.
