Unknown Pitcher Fields

[Gantry]

Now to figure out when U1 comes into play.  Going to put U2 back to OG levels and see when the game changes compared to the original ROM with U1 set to one.

This is awesome, thanks Gantry. Finally we uncover the veil a little bit.

Well, I have a feeling this has already been figured out by someone else but it's fun to get back into RBI stuff either way. 

[Gantry]

U1 is more of the same, the lower the number the more to the left it goes.  The higher the more to the right.  The thing is the difference between 1 and 254 really isn't that much.  So their effect isn't that great, especially when you consider that all pitchers in RBI are in the 105 to 147 range. 

[Gantry]

Next thing to do is give Clemens extreme R curve and check the results.

[nomaaa]

this is fascinating

[Gantry]

Minimal difference setting both curves to 15 or 0, in fact some of it played out exactly the same.  Maybe Clemens doesn't curve it much, but either way  an extreme curve rating doesn't yield an extreme change in the effect of U1 & U2 numbers.

[Gantry]

Edit - I may have screwed up the recording, nvm

[Gantry]

Similar shit with Jimmy Key, the higher the number the more to the right it goes.  He's an extreme lefty pitcher and one of his pitches with U1 set to 1 was WAY outside.  Here's what I know now:

1)  The U1 and U2 values are only used for computer pitchers
2)  Sometimes neither value is used and changing them has zero effect on a pitch
3)  U1/U2 can be used with fastballs, not only with normal speed pitches.
4)  The lower the numbers for both, the more to the left a pitch goes.
5)  The higher the numbers for both, the more to the right a pitch goes.

Probably done for now...

I noticed too that every pitcher has a lower U1 value than U2 value.  But from what I can tell which value, if any,  gets used is random.  U1 and U2 add a random curve alteration to computer pitchers, I'm guessing so they would be less predictable. 

[Gantry]

That also leads credence to the fact that U1 and U2 are pretty much worthless for watch game or fantasy RBI stuff.  The batting AI does  the same thing every time given the conditions of a pitch.  U1 and U2 don't give you better location or anything like that, just varies where the pitch ends up semi-randomly.  But after watching these videos, the computer is going to swing the exact same way and make the same hit as soon as the ball is thrown.  Ergo, I can't see U1/U2 making a lick of difference in fantasy given today's research.  Sorry de snorry

[Gantry]

Also - I think U1/U2/regular are loaded at the beginning of the AB and stay that way, doesn't vary per pitch.  Didn't fully research but the one game I did with Key both pitches to Dykstra were unaffected by U1 and U2.  Ditto with Pettis' first AB IIRC.

Too small of a sample size. I'll be in touch with Peter Lipson before you know it!   

[Gantry]

It's in the threads somewhere I believe, or maybe it was pre forum days, but I did email with Peter 15+ years ago.  Super nice guy but from what I remember he didn't remember a ton of the actual specifics of the algorithms used in RBI.  Also remember he ported this over from Family Stadium - most of the gameplay mechanics were created in Japan.  His job was more to Americanize the game than create the actual game engine.

Somehow I forgot that I posted in there and that this discussion ever took place.

As did I, the brain is a wonderful thing
