str len = 21

split point = 11 (between H and :, ath[splitPoint]:)
substr from 14, length 10 this would 14-24 DOES NOT EXIST
want: substr from 13 length 8
13+8=21

answer: first splitpoint+2, length -2

trying to debug this:

dict.Add(gamResult[i].Substring(0, splitPoint), gamResult[i].Substring(splitPoint + 2, (gamResult[i].Length - splitPoint) - 2));
