@ivan1977uk OK, but I guess there are lots of ways of judging the probability of an event happening. The stats software will tell you what happened in recent matches as an indicator of various trends.
For example, this will show you how to set up a filter that will give you matches with Over 2.5 odds of at least 1.8, where both the home and away teams have scored goals in the first 30 minutes over their last 10 matches.
You might want to increase the percentages to suit your needs, for example you might be able to find matches where over 50% of goals were scored in the first 30 minutes, suggesting a high probability of early goals.
