  * solver.stat and ocean.output are completely unchanged when ln_grid_global=.TRUE.
  * solver.stat is unchanged when ln_grid_global=.FALSE.
- * There are very small differences in the "overall RMS obs minus model of good observations" in the ocean.output when ln_grid_global=.FALSE. is used in the new code. 
-   However, these differences are of the same magntiude as the differences in output the from the trunk when ln_grid_global=.FALSE. is used compared to ln_grid_global=.TRUE.
- * The obs minus background stats calculated directly from the outputted feedback files are exactly reproduced by the new code.
+ * There are very small differences (order 10^-12) in the "overall RMS obs minus model of good observations" in the ocean.output when ln_grid_global=.FALSE. is used in the new code. However, these differences are of the same magntiude as the differences in output the from the trunk when ln_grid_global=.FALSE. is used compared to ln_grid_global=.TRUE.
+ * As an additional check, the obs minus background stats calculated directly from the outputted feedback files are exactly reproduced by the new code to 4 significant figures (they are likely to be exact to higher than 4 significant figures, this is the precision which we use as standard).
