yeah, it's your choice, but the math;

An Illustration:
hypothetical, not a theory in my opinion but highly probable principle.

Suppose we look at one race, and the win pool totals.

Suppose there are 10k in the win pool @ -10 mins to start of race.
by - 2 mins it has gone up to 20k
and we all know it goes up to whatever.

Let's say there are 100 potential systems out there that require a auto-bet implemented.
Not all 100 potential auto-bet systems strike a win on the same race

Let's say out of 100, 80 of those lose and their bets contributed on average
30k
That's $30,000.00 of money that could have been part of the win pool total.
The other 20 won.
And that's just one race.
( size of bet is not taken into consideration at this point of the illustration)

Let's say hypothetically all those 100 separate system where betting on that one race, it's probably an extra 50k - 60k in the win pool.

And that's just the win pool, there's a Trifecta pool, Quinella pool,
Pik 4 and whatever else Pool, ALL missing out.
