ADS1299: Referential montage input filters

Part Number:ADS1299

I am reading section 10.2.2 of the ADS1299 datasheet, and I am not sure what size components to use when designing a circuit for a referential montage. If the input impedance needs to be >10megaohm (as per table 29), does that mean that we make each channel's input resistor at least 10 megaohms, and then choose the value of C to set our bandwidth (i.e. RC = 2pi*f)? Because all the channels are now connected to the reference, does that mean they are in parallel, and is Rfilt (in figure 73) going to change the cutoff?

Thanks for any assistance.
