Can you elaborate on why it makes a difference when the 4 weeks of passing training takes place?
Under the wide assumption that passing cannot be trained as another skill's complementary training, I have to admit it doesn't make any difference.
The real question is whether PA improved (without pops) from other training regimen between those two 2-week sets of passing training, which most believe is impossible.
