P.S. I remembered about an hour later that I put all the settings in the software wiki:

These settings have now (2108) been applied, and the barometer is reporting at ~14sps.
P.P.S. About another 15min later, decided to test whether these settings are retained during power cycles. Found that we needed to reinsert the init_string. This has now been done on the DSM.
