Hi Trenchdigger,
I entered all the IAS openers for all races at Eagle Farm, Moonee Valley and Morphettville on Saturday.
Yes it did take time about 45 minutes, but only 2 runners per race over 4 meetings should not take that long.

Let's look at it this way, if one estimates that there were about 14 runners per race. 45 minutes / 336 runners = .13 of one minute per horse.
So 4 x 2 x 8 = 64 runners x .13 = 8.32 minutes approximately, which is not that long. Especially if it can be done in the morning of the race day.

I had to continually click between the IAS website and the Excel sheet to enter the IAS opening odds for every runner. The Stradbroke and the Derby in Brisbane had 20 runners, but other races had only 11 runners.
Also this was my first attempt of entering all the odds for every race on the 3 remaining meetings after the Sydney washout.

So I could get much quicker in time, and so could you.

I hope I have answered your question.
Regards, Robert
