These are not really anything new to me, I've been experiencing these all the time when batting.
The biggest inconsistency, that often seems to be ignored, is all the variables that go into the match/game. Instead I think people look to the simple solution that will solve everything and mean we all get the same game. The biggest variable being everyone has different abilities and play styles.
Having batted and thought about what I do, why I get so many edges when others get none, I noticed I often play square looking for gaps. I also am fairly loose with my pushing of the defensive trigger. Maybe I'll play the shot before I've fully pushed down for defence. These factors could contribute to it.
Add to this multiple difficulty settings, optional use of markers, people using sliders (a lot of whom probably have no idea the effect changing them will have on their game), pitch, weather, mentalities, quality of deliveries the player bowls etc etc.
