I don't think that wt issue was too clear. Then you would have to adjust every race the horse ever ran. The wt thing is relative. If every horse in the race is carrying 120 why would you need to adjust? The figs are based on 115 and this makes it easier to deal with. I don't know how you would leave the wt unadjusted in the database? Maybe you would want the horses top adjust to today's wt? The only problem is every race has about 25-30% of the horses overweight, what do you do then?
