If you look at the leagues closer you'll find only 2 of the 17 teams won more points away than at home so it's clear playing at home even at this level has its advantages. It's nothing to do with playing in front of a home crowd as you say but more the travelling especially when it's long distances or night games. Players not being able to make it or turning up late due to work and other commitments.
Need to be playing either 2/4 times a season to make it fair for every team, sure that I'll be the case next year if easthouses are out and 16 teams left.
