Teoscar Hernandez edged out Matt Olson in a 120AB practice mode final run-off against Kluber and Paxton/Chapman.
Hernandez had 252 total bases on 80 hits. Olson had 242 total bases, 76 hits.
I created a practice mode team of all CAPs and gave them each a different "meta" swing. I've "tested" about 40 such hitters thus far.
I gave them 10 at-bats apiece against a meta righty and meta lefty, then measured comparable total bases and hits. If they seemed like absolute junk in the first go, I went ahead and eliminated them. While still not a sufficient sample size, guys like Hernandez, Olson, (and to a lesser extent) O'Hearn, and Pete Alonso were markedly better than the guys I eliminated quickly.
Once I eliminated a player's swing, I'd add a different meta-swing to the CAP and then I'd continue getting more ABs with the front-runners -- until a gap in outcome became noticeable enough to once again make some cuts. (Since I am looking for one dominant player-swing, I am not interested in finding out how players rank once it seems they aren't going to be the winner.)
This is how I ended up with Hernandez and Olson in a run-off.
And of the swings I've tested so far, I do feel they were distinctively better for me.
I'm sharing in case the Hernandez swing turns out helpful for you as well.
And also to welcome feedback on improving the testing approach.
And also to welcome suggestions on who you think could give Hernandez a run for his money.
More (Potentially Wrong/Useless, In This Case) Info
Another thing I'm working on is A/B testing different swing adjustments to Hernandez's core swing in order to determine what individual mechanic elements may account for "glitchiness".
One interesting observation so far, is that there seems to be an extremely high percentage of "glitchy" stances with NARROW feet spacing prior to their stride. It also seems like having a closed-ish stance is better than open.
That's about it for now.
Last time I was awake for 3 days, I opened 10,000 packs. This time, I took 1000 practice mode ABs.
