Resistor divider of adjustable ADP7182

Hi, the datasheet of 7182 (and I suspect this question would be relevant for all adjustable ADP71xx)  says "RFB2 must be less than 120 kΩ...", but doesnt mention how low it is allowed to be.

I would like to have -9 V to balance 7102 (strange that ADI doesn't provide such fixed output option), so by going through the resistors availible on market I found a perfect pair at 10200/1600 Ohm. But I am not sure if it is appropriate. Should I perhaps scale it by 5 for 51/8 kOhm or by 10 for 102/16 kOhm?
