Higher values of Rsns will make crosstalk problems worse;
try to keep Rsns to 22K or less if possible.
In general try to keep the QT240 close to the electrodes and
reduce the adjacency of the sense wiring to ground planes
and other signal traces; this will reduce the Cx load, reduce
interference effects, and increase signal gain.

The one and only valid reason to run ground near SNS
traces is to provide crosstalk isolation between traces, and
then only on an as-needed basis.
