Based on the given information, we can make a prediction for the match between Ross County and St. Johnstone. Both teams are currently in the lower half of the league table and have similar form in their recent matches. Ross County have scored 19 goals, while St. Johnstone have scored 15 goals this season, indicating a lack of attacking efficiency. Both teams have also struggled defensively, conceding a combined total of 61 goals this season. Considering that neither team has won a match since December, we can expect a balanced game with a low goal count. Taking these factors into account, I suggest betting on the under total and predicting a low-scoring match.
