Barny, when I find time I will list them (I worked on over 50 races yesterday & cannot recall offhand which they were)

Regards your comment -

"Horses are fit muscular beast weighing say 600kg. To think that 3.5kg, which is 0.58% of it's overall weight is in the top 10 of influencing factors on the outcome of a race is something I cannot grasp at all. It would crap more than that in the mounting yard .......

Maybe weight is in the top 20 of variables, but it's not in the top 10."

- if this had any element of truth to it then why would we have Handicappers or WFA scales etc etc, techniques & theories which have developed over the last century or so??

If weight had no meaning whatsoever then why wouldn't we just let them all run around with whatever on their backs, jeez I might even get a gig, as I used to ride the a heck of a trail pony back in the day

Little hint for you - 'dead weight'
