If you have Video Poker for Winners or Dunbar's Risk Analyzer, they both will do bankroll calculations. Otherwise, I can't improve upon what NOTI already wrote in answer to you question. You need to be made of money to play $5 100.07% DDB with .1% free play for any length of time.
I can't find risk of ruin or bankroll requirements for $5, 100.07 plus .1% slot freeplay for Double Double Bonus.
