I have been looking a bit deeper at this and have decided on a way forward.
I will be backing all qualifying games on Betfair with 2 1pt backs; the first at 1.10 and the second at 1.25 I can put these on prior to the games starting and keeping them in-play when the game starts. I will be using the Over2.5 odds as a filter, i.e. if the over 2.5 odds are less than or equal to 1.8 before the qualifying game starts, then the selection is confirmed.

The graph above shows a 30 point profit from August 1st 2022 to March 15 2023. The slow start is due to waiting for the home team to have played 5 games at home and the same for the away team. The lull in the middle is due to the world cup, causing many leagues to be closed during that period. Interestingly, there was not a single losing bet before the world cup finished which racked up 160 consecutive winning selections.
The period covers 296 selections, with just 5 losing.
The selection process is fairly simple, maybe too simple, in that I am looking for the home team when playing at home have been involved in at least 5 games at home this season of which at least 4 and the last 3 had a goal in the first half. The same applies to the the away team. If either the home or away or both meet the criteria then the games is a selection.
I have made a couple of assumptions that if a game was 0:0 at HT then the odds of 1.25 will be matched and that the 1.10 bet will always be matched. Therefore, the 'profits' shown above will probably be smaller but hopefully are a reasonable reflection. Also I have assumed that Betfair has a market for all qualifying games which is not always the case.
Since the graph above there have been another 19 selections with 1 losing
