Just analysed Saturday 23rd Oct, going through all Saturday gallops using these rules:

1. The horse must have been tipped by both Radio TAB and Late Mail
2. Field must have 8 - 12 horses after scratchings
3. Must be paying $1.5+ 2 minutes prior to jump

Results show that on Saturday the 23rd (Cox Plate Day) after twelve selections there were 8 placings (2 Wins, 6 Places) therefore a 66% strike rate with the total profit being ~+4%

Not too flash, S/R good but not much profit
However, Saturdays are normally tough days to pick further research might find it a handy system for wednesdays and sundays etc..
