This is what I wanted to know, because the details do matter. I don't think you'll get an absolute answer on the hypothetical, because Slow Play is not absolutely defined anywhere and there is no time established for setting dials. One interesting thing is that he commented that you slow played with a swarm. When I play Swarms, I actually feel a little guilty for taking so long, but realize it's harder to set dials for 6-8 ships than it is 2-3.Assuming you've placed your dials and have been waiting the entire time - maybe. Did you ask him if he was ready more than once and did you know it was actually 5 minutes or did it just feel that way?
I think the key is if he actually had dials down and picked them up to change again more than once, I would ask him if there was a problem before calling over the TO. Maybe if he is a new player, he is taking longer than you due to indecisiveness and just needs a prod.
Yes, I had already set my dials.
Honestly I forgot if I told him multiple times. I probably did.
It was actually five minutes. We set a timer on a television at the one LGS this happened at.
He's not a new player.
When I did tell him that he should pick up the pace, I was told in an angry tone something like, "Oh, you want to call the TO over? Dude we have 40 minutes left and it is a crucial turn and you slow play when you play swarm." So I just let it pass because I don't feel like getting in an argument.
The reason why I was hesitant to reply is because I wanted to treat the situation as a hypothetical. The details don't really matter all that much, the question is simply, "Is 5 minutes for a planning phase too much?"
I think this is a good example of why this is subjective and there's not really a good response.
I would guess that you were not intentionally slow playing your swarm and he may not have been slow playing his list either.
I know this is not a definitive answer for you and may be a bit frustrating to hear, but it really is something that is determined in the moment.
I wanted it to be treated as a hypothetical so that it would be more easily applied to future situations. I used to be a proponent of a flat round limit but have been convinced otherwise, so when I come across slow play (very rarely) I don't really know how to deal with it. If I'm going to suggest that we speed the game up and my opponent is going to get butt hurt about it, and then when I suggest a flat round limit I'm told that won't work because one game will hold everyone up (which is correct, this was pointed out to me when an old guy that was new to the game took forever to set up his list and actually play). This is why I'm frustrated. I suppose I could just let him get butt hurt and feed off his anger, lol.
He seemed to imply with his swarm comment that I was inherently slow playing because I fly 6-8 ships often, not because I was purposely slow playing.
