Very interesting question with supporting research from a newbie. I’ll throw some intangibles at you.

How big is your unit versus your tolerance for risk. Judging by your proposed spread, it’s probably high. Example, if betting unit is $5, bankroll is $5000 - you may well be prepared to totally risk $5000. If that unit is $25, or a $25000 bankroll, you are far less likely to throw caution to the wind. Established players tend to take a far higher risk averse approach as bankroll grows.

With a limited roll, game selection is very important. This means decent rules and decent pen which translates to - you can’t afford the higher variance of a crappy game.

Now - is your bankroll fixed or replenishible . In other words, is your bankroll gone if you lose it or do you have monthly funds available to add to your bankroll. So, if you have a sum of money available per month that is unencumbered as in not required for living expense or to debt reduction, you can play as if you have a higher bankroll subject to the following caveats.

You have a betting unit of $5 and bankroll of $5000.
Your monthly replenishment is $500 per month or $6000 per year. You can add your annual replenishable amount of $6000 to your $5000 bankroll and play as if you had an $11000 bankroll PROVIDED that
1. Winnings accumulate and added to the $11000 available.
2. Should you lose those winnings, but still have the unencumbered $500, you may continue to play as if you had an $11000 bankroll.
3. If you should lose winnings + the unencumbered $500 within the then current month, your bankroll drops $5000.
4. When the new month starts, you can then add $6000 to your bankroll subject to points above.
