the whole point of TG figures is because final times at different tracks cannot be accurately compared. Horses that run 1:08 at Del Mar for 6f can get a TG 4 (for example), and a horse at laurel can run 6f in 1:09 and get a 2, so the slower race is actually faster, and without TG you would have no way of knowing. So final times do not mean much to me. If you are old enough to remember the spring meet at belmont in 1973 there were several new track records on dirt leading up to the belmont stakes. Most have been broken since (secretariat still has two records, 1 1/2 miles and 1 1/8 miles). Point is that the track was so "fast" in may and june of that year that final times were very fast, (forego ran an allowance race on belmont day that year, and set a track record for 1 1/16 miles). So final times are usually not truly indicative of true speed.
