Even if we accept all your figures as accurate, you yourself acknowledge that you have put in crazy hours to optimise your model over the summer and spent considerable time each week.
The respective football seasons last 1/2 a year in total.
Even betting the reasonable large sums that you do, you are only looking at ~80k max per year (admittedly tax free).
However, you have also noted that there are a number of you involved.
I struggle to see why you could not obtain a better financial outcome if you were all gainfully employed in the finance industry.
Its not as simple as saying increase the stakes as bookmakers will shut you down.
I'm amazed you can still get anything over $100 down at Luxbet which are one of the tightest bookies around.
Heck I move lines there with $50 bets.
Bookies will shut down successful punters and its only a matter of time.
Larger bets on average also make it increasingly difficult to open new accounts under different names.
So overall, its not impossible to make money from sportsbetting. However, my point is that it takes a lot of time and hard work and most would be able to achieve better utility from a job/business for the same hours spent.
* Holding our current ATS win %, we're expecting a $250K roll going into Brownlow Medal. We then go into college football, NBL and A-League.
* Beating conventional financial markets is an impossibility (or near impossibility). I think this can only be achieved (and I highly doubt that) by institutions with personnel that have multiple PHD's and potentially billions of dollars. You can't compete with outfits that invest hundreds of millions investing into ultra-low latency connections to the market. I've talked about this in the past ad nauseum.
* We're not talking props here. Yeah $50 will move some peanut offering; ie:"Paul Wall over/under 20.5 points", not sides or totals.
* Who says we are not recruiting big squares with losing accounts and big limits . We get our legal eagle to write up a contract and we're in business.
