What percent of players are using HUDs?

[Manimal 42]

I've been searching for this but have not found any discussion.

While playing a $40+4 MTT at UB yesterday (I finished 3rd in a field of 96) I found myself wondering how many of the other players might be using PT and PAhud as I was. I like UB for this as you can still collect data on other tables and when I got to the final table I had reads on nearly 100 hands or more on everyone there.

While other players took a little time to decide how to react to my moves, I wonder how likely it was that they were looking at stats for me.

I've got tonnes to learn about both MTT play and the software but this one question intrigues me. Does anyone know/know how to determine/care to make an informed guess as to how many players in a typical MTT are using tracking and hud type software? I'd love to see some ideas as I'm not sure where to begin on a decent estimate/guess.

Thanks in advance for your response! ;~)
