Hi Paul,
Yes, model congruence reduces the number of bets, but increases the ROI (you win more often, when more models agree on the same runner, the downside is fewer bets). If you are a member of “Smart Betting Club” (?) they have made an in-depth report on our service that explains this further.
There is another option in the spreadsheet that you might like to try… We bet with 6 prediction models, you can leave congruence at “1”, but disable, say 5 of the 6 models. Again, this will result in fewer bets, but will give you a taste of how the system works.
The £2 limit is not enforced by us. This is the Betfair enforced minimum. If you try to submit a win bet with a stake less than £2.00 on Betfair it will be rejected (I might have misunderstood your question here – apologies if so). The minimum stake on BetDAQ is 50p.
Building your bank slowly is a great idea. Again SBC have included a guide on a suggested Bank size (in points), well worth the investment in their joining fee to get access to this report (and see how we compare to other tipsers).
Ref: the refresh rate of 5 seconds… we’ve tested this at lower intervals – unfortunately it causes the spreadsheet code to lock up. This might have been a “feature” of the (intentionally) low spec PC’s we used for testing, by all means try it a try at fast refresh rates, but we can’t guarantee you will always get the tips.
Edit: The recommendation is to use the SP (At present). So the refresh rate is immaterial.
Cheers
Nick
