Poorest day for automation Pre Race

[Korattt]

Overall Tuesday’s?

[Euler]

Tuesday's tend to have different characteristics in comparison to other days. So depending on what your automation does, it may have a stinker on a Tuesday.

But that also varies by time of the year. It's more pronounced during the flat season.

Mon and Tues. But largely due to the reduced amount of money you can turn over rather than the return itself being significantly worse.
