Yes. However not as the masses think.
Most folk are under the impression that heavy going results in less winning Favourites. This is not the case, look at the stats below:
|Going||Run||Win||SR||P/L BF||ROI BF|
|Good To Firm||7310||2400||32.83||-10.92||-0.15|
|Good To Soft||4704||1483||31.53||-91.28||-1.94|
GOOD ground has the worst SR of all the possible goings, and HEAVY doesn’t look so bad. However, for profitability the going that gives you the best advantage is GOOD TO FIRM with a lowely negative ROI of 0.15%
