Thanks Sportz.

I also followed widest barriers regardless of form for a few weeks.

My theory was that by the time it came to the last two races the inside ground had become impacted and rock hard and the wider ground was fresher and easier on the horse.It works, but the run of outs put me off and i started on another plan.

Your method is more targeted and i will give it a go.

Another idea i have is based on horses running together as in a herd.Outside barrier would group with the inside as often the widest horse will compete with the ace draw for the front running position.The horse you fancied was the favourite which would probably also be running handy.It was also the 100 rated horse in theory it had previously done something special.

The above horses would naturally group together and exclude the rest of the field and therein lies the trifecta.

Other horses i throw into the herd group are the topweight and those drawn either side of the horse carrying most of the above factors.
