I don't know about refs being less biased because it's not always the home team that the refs tend to be more biased about. What I did notice due to me liking a bet on the fitbaw is a lot of away teams were winning especially early on when the bundesliga started and I also noticed that yellow or red cards weren't dished out which also could be down to having no crowd on their back
I will be looking at the English leagues starting back to see if the same thing happens and for anyone who likes a bet should take note of the away teams
