https://www.bridgescoreplus.com/zall/anon-300/ will lead you to this enormous matrix, but somewhat lacking, of bridge play info.
I entered the first four deals into a PBN file, and produced a par contract for each. Number four was an eye opener for me.
On the surface it is a simple 3 major bid, and 3 made by N/S. However, the par contracts tell an entirely different story. Par was 3NT by E/W! Par for N/S was down 2! I make that a quick team disaster for E/W.
Then I broke the deals into their daily session increments (initially 11 deals each, later 14 deals each; total 20 sessions). Finally I matched all contracts bid with tricks made.
I can now see clearly what the USBF was concerned about. Match the N/S defensive deal results with their offensive deal results. See if you see a pattern. Imagine yourself as E/W throughout.
Without a complete listing of all 253 par contracts, I am unable to reach a definitive conclusion about this Bertens matter. I am still stuck at 50/50. I am confident I could reach a defensible conclusion with that 253 par info.
All of this addresses the playing partnership in whole. There is nothing at all which points to a single partner. Color me perplexed by this point, at this point.
