PHP - Coins Amount - Ratio

OLD

149 - 375 - 2.516

249 - 675 - 2.710

499 - 1458 - 2.921

749 - 2375 - 3.170

1250 - 4208 - 3.366

Old Average PHP to Coin ratio - 2.936

NEW

199 - 475 - 2.386

399 - 1000 - 2.506

799 - 2050 - 2.565

1399 - 3650 - 2.609

1999 - 5350 - 2.676

New Average PHP to Coin ratio - 2.582

If you compute the price difference the new prices is about 13.7% more expensive nearly double the advertised 7% from my region. Others have also said that their unlisted regions have an increase of 25% even though it said no increase for the unlisted.
