Sorry I'm bombing the forum with simple questions, but I couldn't find an answer to this one straight away.

When filtering for general stuff like effective stacks, no of players preflop, no of players on flop etc - it doesn't matter if I include these in "player" or "opponent" filter right, and I don't need to include them for both?

For general things which apply to the hand then it doesn't matter which section you use as they would be the same for any player in the hand.
I explained the difference between "Player" and "Opponent" filters in your other thread.

Don't worry about asking too many questions - that's what we're here for!
