Is it normal want to share my winning horse racing system with 2 loyal friends

Sorry it's going to be long and thanks for bearing with it.

First of all I don't gamble; for example, when I have gone to Vegas my friends complained I'd wager a roll of quarters and if I lost it all, or won another roll I'd stop. But I am good at math and statistics, so one day I decided to investigate both Poker and horse races, which, by law are both classified as games of skill not luck. Horse racing won out, as I am bad at lying in poker and everyone can see via my body language what I'm holding, etc.

So then I spent literally years studying horse racing statistics, and came up with some astounding loopholes where the public is just not seeing things the way they really are, or alternately are seeing things at the very last minute and I can see all of this via the money flow into bets on particular horses, etc. These are mainly non-Kentucky Derby type races, where there is a lot of confusion going on. This is all done on-line at two major wagering sites (one is backup if the other site crashes).

For months I have kept a record of such wagers, and it has basically come down to the fact that when I cherry-pick the specific races to wager on (about 15-20% of available races) I can win as many as 95% of the wagers, with a profit of about 35-50% per bet, sometimes more. Of course, being a cautious non-bettor, I have resisted the temptation to just stop working and doing this and nothing else. In fact, I have almost never wagered at all, it's mostly on paper and done live with real-time information (not in the papers after-the-fact, as I am forcing myself to feel a bit pressured and rushed when trying to make a snap decision to wager or veto, just like you would feel if you actually went to a track).

It got to the point I couldn't execute it real-time by myself, so I hired someone to assist me one day a week, (a professional person who has a real job in another field and is also a non-gambler). This assistant is in on a profit-sharing thing and we are actually beginning to wager small amounts (better to bet 20 wagers of $2 than do one of $1,000, because the risk is too high that way); for example, a day this past week we made about $23 on 19 $2 wagers (one loss, I bet to Place and it came in to Show) etc. My assistant has informed me that when it totally takes off they are willing to quit their day job - - they believe in it that much. My girlfriend has also put a token amount of money into the wagering accounts, waiting for the proverbial ship to come in.

So it's is apparent that this will make a lot of money (assuming the laws stay the same - and it's totally legal in most jurisdictions including mine, but not in some States). And when it does I want to cut in two dear friends who have not had such an easy ride in life.

So what do I do?
