Xfactor Hitting Systems

@NotebookLM Orientation is still backwards, same as slides.

Hi! For those of you who have been using Cinematic Video Overviews over the past few weeks— what do you think? Any feedback or requests you'd like to share with the team? (Yes, more languages and availability to Free users are on our list! ❤️)

Why the new 2026 ABS height-adjusted strike zone may expose a flaw in chase-rate analysis by treating previously learned, damage-capable upper-zone collision solutions as simple plate-discipline failures. xfactortechnology.com/proprioceptive…

We are pleased to share our CGD and CGD-HH, (power-adjusted) calculator for batted-ball evaluation at the collision level, originally presented at the 2026 SABR Analytics Conference: xfactortechnology.com/cgd-calculator/

@LA_Swiftness I guess it is. Thanks.

@XFactorTechn I’ve seen him hit down and in & up and away for HR’s. If you don’t have eye to see the qualities in his swing that’s on you I guess. 🤷🏻‍♂️

This is a good swing

@MattFritz1307 @LA_Swiftness How profound.

@LA_Swiftness @XFactorTechn It’s a good swing. And there’s also a lot more to hitting than just the swing. I know that’s a tough concept for many to grasp 🤷🏻‍♂️

@LA_Swiftness I know you disagree. That was clear from the first post.

@XFactorTechn Disagree

@CoachLisle Given his rear-leg GRA, his front foot/leg is a brace, not a break.

Murakami uses his front leg like a brake pedal. He slams it down to launch the bat forward. Notice his head? It stays perfectly still. No drifting, no jumping. He's rotating like a door on a hinge. If the head stays quiet, the eyes stay clear.

We had a great time at 2026 SABR Analytics Conference and are grateful to have been presenters. We introduce a new analytics and it was received very well. Watch out deck presentation here: xfactortechnology.com/sabr-presentat…

@SportsTrace That's a 20% gain, not 12%. The gain was 12 mph not percent

+12% Exit Velocity. 60 mph → 72 mph. That’s measurable improvement. SportsTrace helps athletes turn small mechanical adjustments into real performance gains before the season starts. #SportsTech #Baseball #Softball #ExitVelocity #TrainSmart

It's easier to make adjustments when the pitch isn't covering the same ground over time. That's why little leaguers who hit 95mph "equivalent" could not hit a real 95mph pitch. I have several calculators I built that can help you xfactortechnology.com/calculators/ and a free app with several more calculators xfactortechnology.com/x-factor-techn…

Say a 95mph pitch is released from 55ft away (typical MLB release distance) With drag, it has an avg velo of 91.07mph (133.6ft per sec). If I throw a 75mph pitch from 35ft away it has an avg velo of 72.5mph (106.3ft per sec). The "feel" may be similar, but your response has different constraints.

Putting a 75mph machine closer shrinks the reaction window. But the ball still isn’t moving through space like a real 95.

@coachball2709 @LA_Swiftness @DMEASrecruiting This is patently wrong.

@LA_Swiftness @DMEASrecruiting How do you hit 95? How do you hit 75? You have to time them up. How do you time them up? You work on the reaction time. Where it starts in the 60'6 doesn't really matter that much.

@DMEASrecruiting @LA_Swiftness Hitting isn't a reaction so much as a prediction and response. @LA_Swiftness is right. Even if the reaction "feel" is the same, the brain isn't processing the visual information the same and a 95mph pitch covers more ground per second than a 75mph pitch.

@LA_Swiftness What machine did you own that only threw 75? What’s the difference between 90 and 95 to a hitter? The reaction time!! So yes. You can replicate it. How did we ever hit 95 mph if we only had machines that threw 75??

@forcefulhitting @TheHittingVault That depends on your bat lag and the depth of contact. For max power, ideally, you would want complete rotation. That's the point of pelvic deceleration. There's power left on the table if the turn is incomplete.

@XFactorTechn @TheHittingVault Sorry, I didn't phrase that question well. You answered my question, thanks. But, a hitter doesn't necessarily have to rotate - belt buckle to the pitcher - on every pitch. Belt buckle should face the direction of the batted ball?

Trout's back foot doesn't turn towards the pitcher. If that's natural for a hitter to do that's great! BUT there are 3 things that are a must if they don't fully rotate their foot...Check out the full post on our FB page to find out what those are!

@forcefulhitting @TheHittingVault Are you saying the hitter should block the rotation of the pelvis (hips)? I'm confused. What are you asking here? Because a hitter does NOT want to constrict their pelvis. That would cease lower body contribution and move the rotation wholly to the upper body.

@XFactorTechn @TheHittingVault Is what a hitter needs to do - block the pelvis?

@forcefulhitting @TheHittingVault Rear knee, not front.

@XFactorTechn @TheHittingVault I said he might have been late because of his head movement to his rear shoulder, which I believe inhibits his rotation and perhaps is the cause of his alligator arm swing. Not so much on that swing, though. What are you referring to in Ted Williams's front knee?

No, it is a direction issue. His pelves turn becomes obstructed. The "scissor" move or rear foot forward drag is a compensatory move that removes the obstacle preventing the turn of the pelvis. If you drive knee toward pitcher at launch, pelvis is blocked. Clean rotation is demonstrated in GIF

@TheHittingVault Could it be because he's just late?

It's official! We will be the lead-off presenters on opening day at the SABR Analytics Conference. We're introducing Causal Analytics. I hope to someday soon raise hitting causality and architecture to the same level pitching has enjoyed throughout the tech boom.
