I have been watching this thread for a while and wondered if this also had something to do with fitness as the early season results appeared better as a whole. These horses are Hotform and may have been running against lesser fit animals early season.
day 38 – 24/ June saw 80/452 (17.69%) +109.04 (+24.12%)
Since then with yesterdays results (80 Days):
285/1969 (14.47%) +36.22 (+1.84%)
Just a notion.
