Agree with Chuck
I always have a co TD just for dealing with anything that may personally affect me.
Every week weirher it be a league session or bigger tournament I get people telling me I must know all these games so well at The Sanctum and have a huge advantage.
I play 6 games a week there. 4 league games and maybe 2 test games after fixing something. I get there a few hours before anyone. Set up for league. Tune up a few games maybe. Spend the next hour or so divining everyone in and making scoresheets. Play the 4 leagues games ehile being dragged away constantly for rulings and malfunctions (3 DQs this week alone!) after those insoend the next 4 hours fixing more games before I get too tired and kick everyone at after midnight. When a new games comes in I hear people say you brought in another one of yours. I'm not picking that! Reality is I bought it. Fixed it. Stripped and shipped it it and when it was finally done it went to the sanctum. Nothing stays in my house for months so I get a huge advantage. After the first night a games it there everyone else has played it way more than I ever have in months and probobably more than I will in the coming months.
People who dedicate time and effort to create events and create spaces for events will never have an advantage. Any slight perceived advantage is completely offset by distractions and being more fatigued for likely long hours of prep. Running the NEPL finals (with help of course) with 140 or so players across 4 divisions I e been pretty consistent over that past years(3 sessions a year) of being eliminated round 1. When events get to a certain magnitude the distractions just get too high.
I'm just the opposite of think TDs have an advantage and I give Karl extra props for winning over everyone else!
