Took ASC_CHARD_P FM1 (20dB gain) out from guardian, and instead turned on FM9 in ASC_CHARD_P and ASC_CHARD_Y (LP9 - a low pass at 9Hz).

Also added 25Hz-40Hz band stop filters to FM9 of ASC_DHARD_P and ASC_DHARD_Y (called Ncheck). These can safely be engaged in full lock, but they are not in guardian for now.
