I had some spare time because of today's no-racing.

I looked at No 1 and noticed something that amazed me. The Lay system that I noticed and then fine-tuned is this:

1) Only TAB no 1
2) 8 starters or more.
3) Must have won either it's last or second last start.
4) Ignore "spells"
5) No Group or Listed races.

The results for the past six days according to my reckoning are:
Sat - 28 selections for 1 accident ($2.90 Unitab
Sun - 5 selections for 1 accident ($1.90 Unitab)
Mon - 4 selections for 1 accident ($2.90 Unitab)
Tues - 6 selections for 6 smiles
Wed - 12 selections for 12 smiles.
Thurs - 8 selections for 8 smiles.

I also looked to see if any No. 1 horses had won their third-last start - I can't be 100% certain but I'm quite sure there was only one accident and many smiles. I know this might be a temporary anomaly which could soon correct itself, but...

There were 2 qualifying races where no. 1 began at odds-on, they were beaten.

My only explanation is that the increase in weight for a winner in these lower class races could have a negative impact?
