RORBR summary

#1

RORBR is risk of ruin before hitting a royal flush in units of bet per
hand, to convert to dollars multiply by dollars/hand, for example
x$1.25 for 5 coin quarters. RORBR is calculated by solving this
equation: RORBR=SUM[probability x RORBR^(Win)] for each possible Win
and probability, except for the royal flush. Number of bets are solved
for 50% risk of ruin, 10% risk of ruin, and 2% risk of ruin, using the
formula: bets=ln(ror)/ln(RORBR).

Thanks for posting the summary.

It might be clearer to state that your "RORBR" is the risk of ruin
for losing a 1-unit bankroll before hitting a royal flush. Once you
have found that "RORBR", you get the ror for any bankroll from
ror=RORBR^bankroll. (where "ror" is the risk of losing a bankroll
before hitting a RF, and bankroll is expressed in units.)

I know you understand that. But writing "RORBR is risk of ruin
before hitting royal flush in units of bet per hand" didn't make it
clear that it refers to a 1-unit bankroll, IMO.
