The maximum ROR that you will ever face is called your lifetime ROR. As you play more hands, your ROR actually goes down.
Well, your lifetime ROR is a limit applying to losing orig roll assuming you play forever.
It will never go up or down assuming you play forever.
Your lifetime ROR from any point forward is constantly changing.
But, practically, like moo and nazgul suggested, if you double your orig roll, chances of losing from there forward greatly diminish.
If, at some point, you have lost half of orig roll, your lifetime ROR from that point forward is alot compared to original ROR.
The good thing is you can always measure your lifetime ROR at any point in time and go from there.
But, basically, like Nazgul said, if they don't get you early, they probably won't get you.
