How do ROI and ROR relate?

[SuitedSixes]

Help me figure this out . . . I am using hypothetical numbers here. If someone is a 40% ROI $11 player, they make $4.40 per tournament. However, if that same player has a 5% ROI at $110, they make $5.50 per tournament. If someone has the normal goals of making as much as possible while not losing their bankroll, which is the best to play? Do you find the highest level in which you have a positive ROI? Does the lower ROI increase the ROR, or is this an incomplete problem without knowing the standard deviation?
