Why the variable break amount on the same pitch?

RTTS Pitcher - using whatever mode that shows starting and ending position for a pitch. Why is it that, say, using a slider, on one pitch the break indicator will be significantly larger than for the same pitch a couple of pitches later? I see that for my slider, change, and sinker. I can't figure out why the difference from pitch to pitch!

I notice when pitching online my pitchers curveball break degrees will vary from curveball to curveball.

Never understood why.

I *assume* it's just random, i.e. no rating impacts it nor confidence.

I haven't found any sort of pattern to it, and since it's randomness before the pitch is thrown, I don't think it hints to effectiveness either.

It has to do with the pitchers stamina. The break of the pitches become less dramatic throughout the game as the pitcher loses stamina.

You can get two different break angles on the same pitch just by stepping off the rubber and selecting it again.

I see this a lot on curves. One 12-6 goes straight down, another look more like an 11 to 5 (or 1 to 7) curve.

Pitcher isn't tired or close. It could be the first two pitches of the game.

Forkballs, sliders, slurves have similar behavior.

Ah! That makes sense.

Also changes with the pitch location. Curves down in the zone will break more than up. Sliders will have more break when thrown to the glove hand side of the plate.

I've had the suspicion that the break amount shown varies based on how hard you threw the last pitch of that type, the location, and pitcher stamina.
