Just what do sectionals as a tool tell the average punter? Putting a horses sectional time say from the 600m to the winning post per se is meaningless.
The best tool is a good set of eyes!!
If people are basing their punting around the importance of sectionals then they are on the road to hell.
Lets look at what can happen to horse over the last 600m. It could have travelled the race wide without cover, been badly held up, been in need of the run and blew out, the pattern of the race, sit and sprint or all going wide for better ground. Early in the day they may have raced against the rail and gradually moved out further and further during the day. Drawn wide so dopped back, had to work early to get across etc etc. The tempo of their last race won't necessarily be run at their next. Different tracks, surfaces, right handed. left handed. And a biggie, weight. There are too many variables.
Eyes people, eyes, that's the best tool anyone can have.
