I know that it has been a long-standing debate/controversy on stats being 100% accurate as far as yardage, tackles, etc. goes. 

Is there any certain method that member schools are supposed to use when calculating tackles? I know that I have seen many, many games where the total number of "solo-tackles" is sometimes 30-40% higher than the number of plays ran by the opposing offense. Just curious if this was a state by state thing or NFHS method they're supposed to follow.
