S8E3 "Run, Piper, Run" x0.5 ('cause they're identities are different)
S8E9 "Hulkus Pocus" x1
Sub-Total: 2 Episodes & 2 Premonitions (both may seem mathematically incorrect, at face value, but it is accurate due to the "halves" going on)
Grand Total: 61.9 Episodes & 84.8 Premonitions
S1 > S2 > S3 > S4 > S5 > S7 > S6 > S8
S5 (technically) has more premonitions than S4, but S4 has more episodes, for Phoebe to have (at least) one premonition, per episode, so S4 is ranked over S5. This is why I wanted to see how often a season has a plethora of episodes showcasing the sisters powers than just spamming it all in a handful of episodes, that S5 did.
Unfortunately, I'm not a big fan of the S5 episodes where Phoebe DOES get premonitions, unless it's S5E6 "The Eyes Have it". Even then, Phoebe be the only one, in the episode actively using her abilities/powers. Piper's exploding power wasn't working properly, and Paige was only travel orbing -_- I do like Baby's First Demon, though. It's just not a "Protect/Save the Innocent(s)" type of episode, though so there you go.
But, this is about how often Phoebe has premonitions, so here's that list.
