1-- Our foreign figures do not account for ground loss.
2-- Most of the figures over there are based on weight-for-age, there is no simple "zero equals" conversion. A TimeForm 120 for a 3yo filly and a 120 for an older male are two different universes in figure terms. On TG, weight is already built into the past figures, a 5 is a 5, then you adjust yourself for the weight each horse carries today (5 pounds = 1 point).
