If it wasn't for the 6-2 and 7-0 games then we would be looking at a very low scoring competition. If both had been 2-0 instead we'd be average 1.83 goals per game giving a prediction of 117 goals. So anything is possible, a few more 0-0 and 1-0 scores and the average could drop quite quickly.
@Simon R The extra points are the bonus points for predicting the total number of goals in the tournament.
41 goals scored so far so based on the average goals per game that would be 164 in total. You predicted 180 so that would give you 30 minus 16 bonus points =14.
Your bonus points will change depending on the number of goals scored every day.
@Simon R It's just as explained above, but if it's not clear let me know. The first four score columns show the points scored by your teams, the fifth is how close you are to the total goals scored. At the moment it's based on the current run rate scaled up to 64 matches, this figure will change, but I've included it now for a bit of fun.
