The outside barrier or even the inside No1 barrier can be a blessing or equally a curse, depending on the course, distance and field size. The pace style of the horse in an outside [or inside] barrier will also be influenced by the pace style of the rest of the field. Very, very few horses ever are equally good front runners, mid-pacers or backmarkers. They either get a race to suit at the right time, pace and barrier to suit and condt. to suit, or they lose.

Any system based on barrier [any], will naturally throw up winners as at least some horses the system choses are going to suit the barrier, course and distance etc. for that particular race. The 'edge' for the outside barrier is the slightly better prices.
