My version is 2 weeks old, no internet during the cruise. Indeed the ostc was 
set to cylinder 1, that was configured as ean32, the only cylinder in use. Are 
we not getting that info correctly from ostc or are we merging this wrongly? 
All DCs were set to 32%.

BTW was on liveaboard with no land visits..
