Low pass filter for AS5145B

My team wants to try using the AS5145B magnetic encoder as an absolute sensor. Per page 18 on this pdf datasheet, it says we need to make an RC circuit with "R1,R2 ≥ 10kΩ" and "C1,C2 ≥ 2.2µF / 6V," followed by "R1 should be greater than or equal to 4k7..."

Does this mean each resistor should be larger than 10kΩ or the sum of the two should be above 10kΩ with R1 at least 4.7k? Also, for anyone who has used this sensor as an absolute encoder, what size resistors and capacitors did you use and what kind of precision and how much lag did you get?
