Since then, the drop rates have changed, as you can see here, however, the rates are pretty much the same, but with lower rates for Pokeballs and Revives and higher rates for Potions and Super Potions.

The results:

  • Pokeballs: 599 (52.00 %)
  • Great balls: 132 (11.46 %)
  • Ultra balls: 37 (3.21 %)
  • Razzberries: 82 (7.12 %)
  • Total balls/berries: 850 (73.78%)
  • Potions: 134 (11.63 %)
  • Super Potions: 67 (5.82 %)
  • Hyper Potions: 25 (2.17 %)
  • Max Potions: 8 (0.69%)
  • Total potions: 234 (20.31%)
  • Revives: 62 (5.38 %)
  • Max Revives: 6 (0.52%)
  • Total revives: 68 (5.90%)
