I have a spreadsheet which covers all 100 pointers >= $8.30 in Syd and Mel on Saturdays for a 12 month period with columns showing whether they'd won at the distance, how many starters in the race and a few other columns which I can't recall at the moment.
If anybody wants a copy just email me at jacfin@mail.nu.
I'm impressed with your figures for every day Michael. With the number of selections it may pay to raise the minimum price to $10.
Over many years of system following I have found that a hit rate of as low as 10% can be workable and the longest ROO for even that rate would not be expected to exceed 60. A bank of 100 units would probably suffice if the hit rate is maintained.
