Don't take my word for it, try it yourself. Walk up to the dealer and say "Just deal out a few hands without anyone playing. I want to count a few rounds before I decide to play." =)

That is completely up to you. You can play with whatever risk or ruin you feel comfortable with. Everyone's opinion will be different.

If you can replenish your bankroll whenever you take a hit you can use a "trip" risk of ruin formula instead of the standard lifetime ROR formula. That will keep you from going broke on any particular trip, and if you lose a lot of money you will replenish it before your next trip anyway.
I was wondering how much more of a br you need to play 1 on 1 with the dealer in a shoe game leaving negative counts and coming back to a new shuffle. Or how many more top bets if you normally use 50 top bets as your br?
The switch from a full table to heads-up against a shoe game should not change your bankroll requirements noticably unless you also change your approach to the game. Obviously, if you typically wong shoe games, then you will need to switch to play-all if you play heads-up. This will greatly decrease your win rate and/or increase your BR requirements since play-all is a far inferior play method compared to wonging.
