TPS2121: lower ILIM and PR1 to IN1 without divider

Part Number: TPS2121

Tool/software:

Q1: I want to limit current at 0.68A and the calculator says that Rlim should be 200k. But this is higher than the recommended range. Will it work? Why is Rlim kept in a range?

Q2: Is it OK to tie PR1 to IN1 at 5V and CP2 to Ground to always favour IN1 when both inputs are valid? I can save a voltage divider this way. IN1 can never be higher than 5.5V in my real world application and IN2 can either be 5V or 12V but will be OVLO above 5.5V by my OV2 divider.

Many thanks
