Help With A Pick 3 System.. Or Help Fix Mine?

I Use the Basic Adding Of Lets use Todays Number As An Example.. - > (9/4) 414 Daytime in VA 414+414, 414+123, 414+717, 414+939, 999-414, 414+21, 414+51, 414+91... i can usually pull the night time number out of any of the numbers total... but im almost always play a number and im off by 1.. is there anyone that can help me find a new pattern that can help me hit the number spot on... I Also use A Rundown of The Night before, or day before numbers starting with Ex -> 035 and i add 123 to each row until i get back to 035, i use 123, 317 and 163.. idk if that helps.. my methods help me get a number every once and awhile but like i said im usually playing 1 off.. any suggestions?

If your system is predicting numbers that are only 1 off on a semi-consistent basis, then stop playing those numbers and play those number +/- 1.  Simple example using variables:  Your system develops numbers to play such that "xxx", if those numbers tend to be off by 1 then take "xxx" and play "xx(x +/- 1)" or "(x +/- 1)(x +/- 1)(x +/- 1)"  (Not sure what you meant by off by 1, use whichever version is accurate based on your experience).  Also a quick note, I don't know what your experience has been but every number you show is addition is except 999.  You don't have to subtract a number from 999, you can add without carrying the one.  For example 999 + 414 = 303 (instead of 585).  Whichever works for you (or both), just thought I'd point it out.
