How to Get Started ? - Hong Kong races

[davidku]

Hi,

I am pretty new to pace handicapping and I have historical sectional time and paceline for Hong Kong races.

Since I do not have any speed rating, I understand that I need to calculate ITV and DTV.

Could anyone provide me some pointers how to derive the formula ?

Thanks ...
