Re: PCI Change
"This is a purely visual change to how PCI size is displayed....The hitting engine itself splits off Contact, Vision, and Power as individual components for evaluation and this change does not affect that".
Sounds to me like Brian changed the visual display to more accurately reflect how PCI is calculated by factoring power into the equation - a visual change but not a gameplay change.
The interesting part - K/9 and H/9 are the modifiers to contact, vision and power. I never knew that. He doesn't post often but when he does I learn more than from anybody else.Last edited by tessl; 02-24-2014, 03:07 PM.≡Comment

Re: PCI Change
This is why I used the precise wording "correlates more closely". It's purely an illustrative statement, as it would take pages to explain it precisely.
the PCI size now correlates more closely with OPS, rather than AVG
This is a completely true statement. The combination of Contact, Power, and Vision has a high (but not 100%) correlation to OPS. In fact, Vision by itself has a high correlation with Contact, but they are different things.
Let me ask you something even more counter-intuitive. What correlates the most, by far, to BB%? It's not Contact or Vision. You're assuming I assumed that Vision was the contributor to BB%, but it's quite the opposite. It's Power.Last edited by Brian SCEA; 02-24-2014, 03:29 PM.Comment

Re: PCI Change
Yeah like other guys are saying, it's only the PCI visual that gets changed, so how all the major attributes (Contact, Vision, Discipline, Power, etc.) contribute to the hitting results do not change much, I think.
The new PCI would be more informative since it will better correlate with our experience, that power hitters in the game tends to produce more hits than weak hitters, given everything else equal. But it could also emphasize the limitation of the current game engine.
Like if you create a Tony Gwynn (or Ichiro for that matter) in most video games, a hitter like that is usually not capable of hitting for a very high average unlike in real life, since Power does have a very significant effect on producing safe hits in video games. But Tony and Ichiro aren't power hitters.Comment

Re: PCI Change
Just to give more background information..Some people were pointing out that the "best" hitters weren't always getting assigned the biggest PCI. I.e. the PCI represents contact/vision, leaving power out. This worked fine for the hitting engine, but visually it makes more sense to include power because this is how the pitcher thinks when he decides how to pitch to the hitter. Only the more sophisticated users understood why the PCI was higher for contact hitters than pure power hitters, and this change hopefully helps resolve that confusion for everyone.
This style of pci size relates to how much "threat" the batter is generating at the plate, leading the pitcher to pitch around. Power hitters also cover more of the plate than their contact alone allows, because in crude terms they can turn a bad hit into a good hit (ex. a hit to the warning track becomes a home run). In technical terms though, the hitting engine doesn't think this way. It first gives contact hitters better contact, and then adds on power for the extra swing speed of power hitters. The old PCI represented this concept faithfully, but it's arguably harder to explain than the new system.Last edited by Brian SCEA; 02-24-2014, 03:34 PM.Comment

Re: PCI Change
The one with a 1.000 2-season OPS?
He also has a .258 AVG. The question is should he have a small or big PCI? Last year, below average. This year, above average. There's no wrong answer until we define what we want PCI to mean to the user.
The hitting engine considers him a below average contact/vision guy, and will give him below average contact for hitting the ball. It will then add a lot of power to his hits.Last edited by Brian SCEA; 02-24-2014, 04:06 PM.Comment

Re: PCI Change
@Brian,
1. Thanks for getting back and sharing. That is what makes you SCEA guys the best out there
2. Sort of disappointed that we cant move the PCI. Maybe something to think about for MLB 15. I heard someone say they don't like cursor hitting. I personally do. It makes me feel more in control. But I am glad you at least cleared it up
3. I think the old one made a lot of sense. I always viewed PCI as sort of the persons ability to make solid contact. An Ichiro type makes solid contact and doesn't strike out much. However, what happens when the contact is made is determined by the Pwr rating. In my mind...someone like say a Richie Sexon type may have a small PCI...but if you get it in the PCI it might go for a ride...but a lot of whiffs are possible. The new...is just another way...but now I know. I would have raised an eyebrow if Soriano ended up with a huge PCI if I didn't understand it now.
4. Is the PCI change optional. I personally liked your originally representation.Comment

Re: PCI Change
I'm curious as to what exactly you mean by moving the PCI while you swing. I feel like you have pretty good control of the PCI movement up until the last moment when you swing. Its a very, very short time between pressing the button to swing and hitting the ball.
Are you talking about guess pitch, how it locks the PCI in place?Comment

As long as it blends realistically , statistically and feels right I think thats all we can ask for from a video game when trying to Bat .

Re: PCI Change
considering he's the senior AI programmer, i believe he's the one behind all these kind of changes, so it'd make sense for him to be able to accurately explain how it works. (not taking credit away from you Brian), just saying. You are still awesome with your responses.
