I made a study a while ago over a period of 5 months...not much I know but was just testing out what someone wrote here that maiden favourites win quite a few of the first two races at a meeting. With a small number of filters, 1st-4th last start, within 5L of winner or won last start, started within one month of last start, age to 5yo, maidens and R65 races in New Zealand. Worked very well when using those filters and if the favourite did not qualify, the 2nd favourite was looked at for qualification. Where the dividends were too close to split (say 20c), both were backed.

Also noticed that the distance range 1950-2200m was running at 50% win strike rate.
