This is obviously some kind of stall tactic/ way to make it less likely to happen. You are probably well versed in this tactic over the years and understand it well. It's easy to see from reading these forums how many in-person meetups actually take place with certain people, especially when there's some type of challenge or whatever going on. You know darn well that most Advantage players have issues with your identity being given up especially when there's zero value. Oftentimes people think it's Advantage players trying to protect themselves from the casinos knowing their identity but that's not entirely the case it's only part of it.
There are Advantage players who would rather remain as unknown as possible so other Advantage Players don't spot them in casinos and then get nosy and possibly intrude on their play.
Timelines and schedules just don't magically line up and people don't want to spend the cost to have a debate over something that probably isn't going to bear any fruit in the first place. People who love these in-person interviews usually have something to gain or promote. You have something said something like this before, and I have seen it from other people. They are always wanting to get people in a room for some weird reason.
I have not been shy about meeting people in person, I met over 100 people from the forums. I Know Dan isn't shy about meeting people either. If we can get Dan and whoever else to agree. Assuming it's convenient(In Las Vegas) I would be willing to do so if I'm able to invite(and they agree) a professional sports bettor or someone in the industry who has knowledge of sports betting math and some of its history.
This is all assuming nothing comes to light that makes me believe it's a bad idea, while that's rare, I have been in situations where the situation was going to be -EV.
