You would lose that bet. John Sexton was one of Kodak's main
consultants on their films. And they tuned the films based on his
experience with them. I was also a beta tester of TMY, TMX and P3200
for Kodak. One interesting point he made was that TMax developer has
such great longevity that even at high dilutions he was able to process
his film in full tanks, rather than in tanks with only half the number
of rolls they normally take, like would have to be done with dilute
HC-100 or D-76 or whatever.
His prints are gorgeous for a very good reason. He's a master of the
medium. There is no magic to it. If you do what he does, you'll get the
same results he will (technically, not necessarily aesthetically).
Check out his book "Places of Power" where he used his special
techniques. You have to be very careful with low dilution processing.
Sexton uses a Jobo Processor and temperature controls it. I also always
used temperature control with my black and white film. But then I
usually processed it at Kodak's recommendation for optimum quality - 75
degrees for TMY and TMX and 85 for P3200. Not ideal for processing at
room temperature without any temperature control.

His bad opponent's "facts" he sweeps away,
And drags his sophistry to light of day;
Then swears they're pushed to madness who resort
To falsehood of so desperate a sort.
Not so; like sods upon a dead man's breast,
He lies most lightly who the least is pressed.
