It all depends on how much money you bet a week? I average 30 bets a nite, so for the week that is over 200 bets. Now if you bet $500 a bet (which is how I would do it with a 100k bankroll, gives you a 200 unit bank) over 200 weekly bets that means you are putting a little over $100,000 a week thru the books and if you win at a 1-2% rate (which is what I have won at for almost 2 years) than you would make 1-2k a week.
If only it was that simple. Bottom line variance will be tough on most. But if you can handle the ups and downs (which most cant, IMO), you would then need to find enough plays, which takes a lot of time, effort and outs.
To answer your question, yes. None of the math behind this is unrealistic. It would be some other things you would have to deal with but that would very close to how I think a person with a 100k bankroll would perform if they were making +ev bets all day.
