That is absolutely possible, Christian. I think we should limit the conversation to live tournament matches, disregarding on-line play which can be subject to all sorts of chicanery.
MCG posted the lowest PR that I am familiar with (varied between 0.99 and 1.11 depending on analysis settings) in an 11-point Dual Duel match in San Antonio this January.
Numerous other players have posted 1.0Consistency is also a consideration to ensure a great match. If we eliminate Falafel from the discussion as he is listed as the commentator, I would suggest that MCG, Mochy, and Michi are the most proven consistent low PR performers in live match play. Thus my suggestion.
